Every common mistake was addressed.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eThe ducting problem nobody else solves.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe most common error in aftermarket top mount intercooler design is supplying a larger core without properly sized ducting to match. Fitting a larger intercooler and leaving the factory bonnet splitter in place means a significant portion of the new core receives no ambient airflow whatsoever. It is a pointless exercise.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Process West solution is a purpose-built bonnet splitter sized specifically for the upgraded core, ensuring 100% of the core receives full ambient airflow. Combined with the intercooler, it is the most complete and capable top mount intercooler option available for the GC8.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eLargest core on the market.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAt 490 x 175 x 90mm, the Process West core is by far the largest top mount intercooler available for the GC8 platform. The 90mm core thickness is a deliberate engineering choice, balancing maximum cooling surface area with the airflow resistance characteristics of a bonnet scoop mounted intercooler, delivering lower outlet temperatures and more power where it counts.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe definitive top mount intercooler upgrade for the Subaru GC8 WRX and STI.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation guide:\u003c\/strong\u003e \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0962\/0570\/1399\/files\/Top_Mount_Intercooler_-_Subaru_97-98_GC8_WRXSTI_PWTMIC01B.pdf?v=1777623356\" target=\"_blank\" rel=\"noopener\"\u003eView install guide\u003c\/a\u003e\u003c\/p\u003e","brand":"Process West","offers":[{"title":"Black","offer_id":62794697474129,"sku":"PWTMIC01B","price":1470.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2115\/6365\/files\/14_9f079cf8-e0c8-47d6-827b-0a680eed2ac3.png?v=1791064095","url":"https:\/\/longboostperformance.com\/products\/top-mount-intercooler-subaru-97-98-gc8-wrx-sti","provider":"LongBoost Performance Parts","version":"1.0","type":"link"}
