As this figure shows, IRIDIUM TT can reduce the Pmi COV approximately 3.1% and accordingly reduce fuel consumption by 2.4%, compared with the Iridium Spark Plug. These advantages are achieved because the miniaturization of the ground electrode enables better ignitability, improving combustion efficiency. 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.

Normally, this can be accomplishing by widening the spark gap, however this causes spark voltage to increase, which has the opposite effect.

This enables high-response driving with fewer misfies than under higher required voltage spark conditions, and fewer misfies when ignitability is difficult. As a result, acceleration improves in comparison with normal plugs.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eImproved Horse Power (2):\u003c\/strong\u003e\u003cbr\u003e The 0.4mm center electrode increases output under various driving conditions.\u003c\/p\u003e \u003cp\u003e\u003cimg alt=\"\" src=\"\" style=\"width: 316px; height: 235px;\"\u003e\u003c\/p\u003e \u003cp\u003eThe power produced by the 0.4mm dia. iridium center electrode is IRIDIUM POWER unmatched by other plugs.
