Because the IRIDIUM TT is low in combustion variation and enables a reduction in idling speed, further improvement can be expected in fuel efficiency.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eVehicle Fitment:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e  \u003cli\u003e2006-2007 Subaru WRX EJ25 (Stock Heat Range #6)\u003c\/li\u003e  \u003cli\u003e2008-2014 Subaru WRX EJ25 (Stock Heat Range #6)\u003c\/li\u003e  \u003cli\u003e2006-2007 Subaru STI EJ25 (Stock Heat Range #6)\u003c\/li\u003e  \u003cli\u003e2008-2014 Subaru STI EJ25 (Stock Heat Range #6)\u003c\/li\u003e  \u003cli\u003e2015-2021 Subaru STI EJ25 (Stock Heat Range #6)\u003c\/li\u003e  \u003cli\u003e2003-2008 Subaru Forester XT EJ25 (Stock Heat Range #6)\u003c\/li\u003e  \u003cli\u003e2008-2013 Subaru Forester XT EJ25 (Stock Heat Range #6)\u003c\/li\u003e  \u003cli\u003e2007-2009 Subaru Liberty GT EJ25 (Stock Heat Range #6)\u003c\/li\u003e  \u003cli\u003e2010-2014 Subaru Liberty GT EJ25 (Stock Heat Range #6)\u003c\/li\u003e  \u003cli\u003e2007-2009 Subaru Outback XT EJ25 (Stock Heat Range #6)\u003c\/li\u003e  \u003cli\u003e2010-2014 Subaru Outback XT EJ25 (Stock Heat Range #6)\u003c\/li\u003e \u003c\/ul\u003e","brand":"Denso Auto Parts","offers":[{"title":"Default Title","offer_id":48832795509039,"sku":"IKH20TT-4","price":75.96,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/3903\/9279\/files\/IKH20TT-4.jpg?v=1709769095"},{"product_id":"denso-iridium-power-spark-plug-8-heat-range-4-pack-subaru-ej25-vw-audi-ea888-gen-3-ikh24","title":"Denso Iridium Power Spark Plug #8 Heat Range 4 Pack","description":"\u003cp\u003eDenso Iridium Power - A next-generation spark plug that draws out engine evolution with a high-performance spark for improved acceleration.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFor drivers that care about performance.\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eBy using a 0.4mm diameter iridium alloy center electrode and a special ground electrode, IRIDIUM POWER realizes spark performance unseen until now.

Like all GFB pulleys, the material used is 6000 series aluminium alloy billet, which nets a large weight saving of 1.4 kg over the factory pulley, without sacrificing strength or reliability.  The kit comes complete with the required serpentine belt, and installation is dead easy Ð no specialized tools are required and it can be done in as little as 30 minutes. The accessories are under-driven by 20%, which does NOT compromise their performance at low RPM, but does help reduce parasitic losses at high RPM.  Like all GFB lightweight under-drive pulleys, the improvement to the car is felt in the form of sharper throttle response (particularly off boost), and the engine feels more willing to rev. A useful comparison is the difference between performance on a cool evening vs. a warm day, or having the A\/C off vs. on.MITSUBISHI Lancer EVO IV-IX 96-07 CT9A 206kw Petrol Engine FWD Sedan 03\/01-03\/03 MITSUBISHI Lancer EVO IV-IX 96-07 CJ-CP_ 206kw Petrol Engine AWD Sedan 08\/98-08\/01 MITSUBISHI Lancer EVO IV-IX 96-07 CT9A 202kw Petrol Engine FWD Sedan 01\/03-03\/05 MITSUBISHI Lancer EVO IV-IX 96-07 CN9A 206kw Petrol Engine FWD Sedan 08\/96-01\/98 MITSUBISHI Lancer EVO IV-IX 96-07 CT9A 214kw Petrol Engine FWD Sedan 03\/05-10\/07 MITSUBISHI Lancer EVO IV-IX 96-07 CG, CH, CJ 195kw Petrol Engine AWD Sedan 03\/04-on MITSUBISHI Lancer EVO IV-IX 96-07 CP9A 206kw Petrol Engine FWD Sedan 01\/98-12\/99 MITSUBISHI Lancer EVO IV-IX 96-07 CP9A 246kw Petrol Engine FWD Sedan 01\/99-01\/01 MITSUBISHI Lancer EVO IV-IX 96-07 CG, CH, CJ 206kw Petrol Engine AWD Sedan 01\/06-on MITSUBISHI Lancer EVO IV-IX 96-07 CT9A 194kw Petrol Engine FWD Sedan 03\/01-03\/03\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-Lightweight-Underdrive-Crank-Pulley-w-Belt-Mitsubishi-Evo-4-9-2011\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":48886636314927,"sku":"2011","price":310.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/3903\/9279\/files\/2011.jpg?v=1710119502"},{"product_id":"gfb-wastegate-fitting-kit-1-8-bspt-to-an-4-stainless-steel-3847","title":"GFB Wastegate Fitting Kit 1\/8\" BSPT to AN-4 Stainless Steel","description":"\u003cp\u003eGFB Wastegate Fitting Kit 1\/8\" BSPT to AN-4 Stainless Steel\u003c\/p\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":48886636380463,"sku":"3847","price":25.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/3903\/9279\/files\/3847.jpg?v=1710119501"},{"product_id":"gfb-25mm-bov-inlet-hose-adaptor-5325","title":"GFB 25mm BOV Inlet Hose Adaptor","description":"\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-25mm-BOV-Inlet-Hose-Adaptor-5325\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-25mm-BOV-Inlet-Hose-Adaptor-5325\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":48886636511535,"sku":"5325","price":31.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/3903\/9279\/files\/5325.jpg?v=1710119501"},{"product_id":"gfb-lightweight-underdrive-2-pulley-kit-subaru-wrx-sti-01-02-2001","title":"GFB Lightweight Underdrive 2 Pulley Kit","description":"\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-Lightweight-Underdrive-2-Pulley-Kit-Subaru-WRX-STI-01-02-2001\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003cp\u003e\u003cspan style=\"font-size: small;\"\u003eGFB lightweight pulley kits are made from aircraft-grade 6061-T6 aluminium and offer faster acceleration through significant weight reduction on the crankshaft.\u003c\/span\u003e\u003c\/p\u003e  \u003cp\u003e\u003cspan style=\"font-size: small;\"\u003eMost of our kits are underdriven, which means the accessories are driven slightly slower to reduce parasitic losses.

As with our WRX kit, the GFB STi short shift kit includes a unique clamp arrangement that allows the shift throw to be reduced much more than by changing the gearstick alone. As you can see from the picture, the GFB clamp eliminates the need to lift the gearbox linkage higher to reduce shift throw. Instead, you simply select one of the three holes.  4002-2The factory shifter in an STi has a shift throw of 40mm per gate; the GFB unit is adjustable from the factory setting, right down to a tiny 22mm per gate! To put this into perspective, the best any aftermarket shifter (that replaces only the gearstick) can hope to achieve is 30mm per gate, without modifications to the linkages or surrounding bodywork.  The photos opposite show the stock STi shifter vs the GFB shifter from 3rd to 4th gear.  Installation is done completely from within the car, and is made much easier with the inclusion of a special tool for removal and installation of the reverse lock-out cable pin.

The Atomic Boost Controller was tested on an MY02 Subaru WRX (whose only mods were a turbo-back exhaust) back-to-back with the factory controller. A base-line power run was performed with the factory boost control, and the boost level was measured at the same time. The Atomic was then installed and set to the same peak boost level of 0.9bar (13.2 psi) so that the spool-up time could be accurately compared before and after the installation. The dyno graph shows the Atomic boost curve in green, and the factory curve in blue. 4th gear is used for both tests, and proof that the Atomic was set to the same peak level is seen towards the end of the chart as the two curves meet. However, notice the massive gains down low in the rev range, as much as 18kW (23.4hp) AT THE WHEELS! This increase in power shows that the Atomic allows the boost to rise significantly earlier than the factory controller, which on the road represents much better acceleration from a whopping 1700RPM earlier in the rev range. All this WITHOUT exceeding the factory peak boost level, and for a pocket-money price! 3001-2 It is important to note that the MY01-02 (MY02-03 in the US, GDA chassis) model responds very well to this modification, because the factory boost mapping is very conservative in an attempt to keep the torque curve flat and the power delivery linear (which totally kills the feeling that you are driving a turbo!). Note of course that boost can be increased above the factory level for more power gains, but the purpose of this experiment was only to show the improved spool-up potential on this particular model WRX. So, if you want your GDA WRX to REALLY feel lively, fit an Atomic or Reactor boost controller for the best Ã’bang-for-your-buckÓ modification you can make!\u003c\/p\u003e \u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-Atomic-Single-Stage-Manual-Boost-Controller-3001\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":48886637658415,"sku":"3001","price":107.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/3903\/9279\/files\/3001.jpg?v=1710119501"},{"product_id":"gfb-lightweight-underdrive-3-pulley-kit-subaru-wrx-99-00-sti-99-00-forester-gt-01-02-2002","title":"GFB Lightweight Underdrive 3 Pulley Kit","description":"\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-Lightweight-Underdrive-3-Pulley-Kit-Subaru-WRX-99-00-STI-99-00-Forester-GT-01-02-2002\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003cp\u003e\u003cspan style=\"font-size: small;\"\u003eGFB lightweight pulley kits are made from aircraft-grade 6061-T6 aluminium and offer faster acceleration through significant weight reduction on the crankshaft.\u003c\/span\u003e\u003c\/p\u003e  \u003cp\u003e\u003cspan style=\"font-size: small;\"\u003eMost of our kits are underdriven, which means the accessories are driven slightly slower to reduce parasitic losses.

Our unique system means that not only is the shift throw distance fully adjustable, it can be reduced more than any other brand by a long shot (at the shortest setting, the throw from 3rd to 4th is a mere 55mm, or 2.15 ), whilst retaining the stock gearstick height.If you want a race-car feel when you change gears, look no further than a GFB short shift kit, the shortest throw shifter on the market!..SUBARU STi MY08-13 GE 169kw Petrol Engine AWD Hatchback 01\/08-on SUBARU WRX MY08-14 GE 169kw Petrol Engine AWD Sedan 12\/00-08\/07 SUBARU WRX MY08-14 GEB 169kw Petrol Engine AWD Sedan 01\/08-12\/11 SUBARU WRX MY08-14 GH 195kw Petrol Engine AWD Hatchback 08\/07-12\/11 SUBARU WRX MY08-14 GH 169kw Petrol Engine AWD Hatchback 08\/07-12\/11 SUBARU WRX MY08-14 GH 169kw Petrol Engine AWD Hatchback 08\/07-12\/11\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-Adjustable-Short-Throw-Shifter-Kit-Subaru-WRX-08-14-5MT-4005\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":48886637560111,"sku":"4005","price":283.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/3903\/9279\/files\/4005.jpg?v=1710119502"},{"product_id":"gfb-d-force-diesel-electronic-boost-controller-kit-3006","title":"GFB D-Force Diesel Electronic Boost Controller Kit","description":"\u003ca href=\"https:\/\/www.prospeedracing.com.au\/GFB-D-Force-Diesel-Electronic-Boost-Controller-Kit-3006\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003cp\u003eINTRODUCING THE NEW GFB D-FORCE - THE DIESEL SPECIFIC ELECTRONIC BOOST CONTROLLER WITH EGT SENSOR!

We then anodize them black for a stealthy appearance and superior wear resistance.  This kit is supplied with 3 pulleys, not just for looks - the combined saving of 2.2 kg is significantly more than what is achieved by replacing just the crank pulley alone.  The weight doesnÕt tell the whole story either - even though the saving is a significant 77%, the actual rotating inertia reduction (inertia is what counts) is 83%.
