We tested both stock and tuned vehicles to evaluate the impact of switching to a less restrictive intake version. As the naturally aspirated 2.4L boxer engine is sensitive to intake air temperatures, our initial priority was to ensure a fully sealed system. Dyno testing revealed that the stock ECU causes a power drop around 6000 rpm. This power drop persists regardless of the intake configuration. Even with all restrictions removed, the high airflow volume causes strong engine resonance at this rpm, resulting in a momentary power drop below the stock curve. The stock airbox provides a mysterious benefit at this rpm, but it also restricts power at higher rpm. After iteratively testing various intake lengths, single and dual duct openings, and even the addition of baffles, we arrived at a version that minimizes the resonance dip while increasing peak power by 14 hp on the stock ECU. Tuning the ECU results in significant power gains in the mid-range and eliminates the power drop below the stock curve.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Eventuri Difference\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe GR86 Eventuri system utilizes our patented carbon fiber housing, providing an aerodynamically efficient airflow path from the filter to the turbo. This is not just a cone filter with a heat shield; it is a unique design that induces the Venturi effect and maintains laminar flow to reduce turbo drag. Please see \u003ca href=\"http:\/\/www.eventuri.net\/technology\/\"\u003ehere\u003c\/a\u003e for more details on the design and mechanics of the housing.\u003c\/p\u003e\n\u003cp\u003eThe filter housing consists of a bespoke second-generation filter, an aluminum inlet cowl, and an integrated airflow section. The carbon pod covers a reverse-mounted filter, smoothing the airflow to the airflow section and connecting to the rear inlet tube. This changes the airflow path from the stock airbox. Airflow entering from the front of the airbox makes a 90-degree turn to pass through the panel filter, then another 90-degree turn to pass through the airflow section. Our system achieves a more direct flow because the airflow enters from the front of the filter housing and flows to the airflow section without sharp directional changes. As a result, the airflow path from the filter to the turbo inlet tube is smoother, reducing turbo drag. We use a CNC-machined mount fixed to the carbon housing to ensure a secure seal with the mass airflow sensor.\u003c\/p\u003e\n\u003cp\u003eThe ducts channel ambient air from the front bumper\/grille section into the filter housing. After several trials, we found that a dual intake that draws cold air from both openings in the slam panel area works most efficiently. The front bumper area is filled with cold air from our scoops and the natural design of the stock cavity behind the bumper. The ducts feature extended rubber seals that integrate with the filter housing to prevent hot engine bay air from entering the intake while allowing for engine movement. It is mounted in three positions for a secure fit.\u003c\/p\u003e\n\u003cp\u003eThe final components are two front scoops located behind the lower grille, which direct ambient air upwards into the duct openings. This keeps IAT (Intake Air Temperature) low while driving. Even if you cannot use the scoops due to an aftermarket oil cooler, the IAT is kept to a minimum as the air behind the bumper is naturally saturated with cold air.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The engine cover is not included with the intake system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEach intake system includes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003ePatented carbon fiber Venturi filter housing (with integrated airflow section)\u003c\/li\u003e\n\n\u003cli\u003eBespoke high-flow dry cone filter\u003c\/li\u003e\n\n\u003cli\u003eCarbon fiber dual-feed inlet duct\u003c\/li\u003e\n\n\u003cli\u003eLaser-cut front air scoops\u003c\/li\u003e\n\n\u003cli\u003eCustom-made hardware\u003c\/li\u003e\n\n\u003cli\u003eLaser-cut stainless steel brackets\u003c\/li\u003e\n\n\u003cli\u003eCNC-machined MAF boss and bracket mount\u003cbr\u003e\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eBefore Ordering\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e〇 About Import Consumption Tax\u003cbr\u003eAt the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.\u003cbr\u003e\u003cbr\u003e〇 Confirmation of Compatibility\u003cbr\u003eOur entire product database is based on North American vehicles (USDM).
