This added heat reduces air density thus reducing engine power capabilities. Phenolic Spacers are able to withstand 500+ degrees F. Subaru engines run at the hotter end of operation around 200 degrees F, so the Phenolic Spacer is well within its max running temperature. GrimmSpeed has tested that it is also safe to run race fuel, E85 and methanol with the Phenolic Spacers.\u003c\/p\u003e\n\u003ch4\u003eFEATURES:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eGreatly\u003cspan\u003e \u003c\/span\u003ereduces\u003cspan\u003e \u003c\/span\u003ethe transfer of\u003cspan\u003e \u003c\/span\u003eheat\u003cspan\u003e \u003c\/span\u003efrom engine to intake manifold thus reducing heat soak.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eOne-of-a-kind true Phenolic material, not cutting board material like others.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eThe cooler your intake temperature is, the denser the air is which leads to more power.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFor every 5 degree reduction in air temperature, increases power by 1%.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"table-scroll\"\u003e\n\u003cp\u003eCooler and denser intake air, increases the amount of air that can be mixed with fuel thus increasing efficiency.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"table-scroll\"\u003e\n\u003cp\u003eDirect bolt-on\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"table-scroll\"\u003e\n\u003cp\u003eUSA made\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFITMENT\u003cbr\u003e\n\u003c\/h4\u003e\n\u003cp\u003e2002-2014 WRX\u003c\/p\u003e\n\u003cp\u003e2004-2021 STI\u003c\/p\u003e\n\u003c!----\u003e","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":43717905449004,"sku":"019001","price":55.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0374\/6149\/1756\/files\/cdb9251decaf61b3a2f7f752f0b33b4c.webp?v=1723493434","url":"https:\/\/wrxdaily.com\/products\/grimmspeed-8mm-intake-manifold-phenolic-spacer-pair-2002-2014-wrx-2004-2021-sti","provider":"WRXDaily","version":"1.0","type":"link"}
