The Cobb Redline Carbon Fiber Intake is the perfect blend of performance and style for your 2015 - 2021 Subaru STI. Crafted from 2x2 twill carbon fiber and coated with a high - quality gloss finish, it's a real eye - catcher in your engine bay. Key features include a 2x2 twill carbon fiber weave, a top - notch gloss finish, exclusive COBB Redline badging, an integrated carbon fiber scoop, compatibility with COBB OTS maps, easy installation, and an installation guide. However, tuning is required. The multi - layer 2x2 twill carbon fiber airbox offers a genuine carbon intake experience. The gloss finish resists fading from heat and UV light. A unique black Redline badge adorns the intake ducting. Air is filtered through a 35% larger pre - oiled filter than the standard SF Intake and routed to the MAF housing via a black anodized billet aluminum adapter. The wire - reinforced black silicone coupler, sealed with black anodized clamps, gives a sleek look. You can remove a billet plate on the fender side of the airbox to boost airflow and make the intake sound more audible. The intake system has special features to maintain optimal flow and reduce turbulence. A custom conical air - filter, a CFD - designed velocity stack, and a unique air flow straightener grid smooth the air flow for accurate readings. The one - piece high - temperature plastic composite design saves weight and cuts down heat transfer.
Using this Cobb Redline Carbon Fiber Intake is straightforward. First, follow the included installation guide to install it in your 2015 - 2021 Subaru STI. Remember, tuning is required after installation to ensure the best performance. When using your car, the intake will enhance the engine's air intake, which can improve performance. As for maintenance, regularly check the pre - oiled filter. If it gets dirty, clean or replace it as needed. Also, inspect the black anodized clamps and the silicone coupler for any signs of wear or damage. Make sure the billet plate on the fender side of the airbox is properly secured if you choose to leave it in place, or if you've removed it for more airflow, check the area for any debris. Keep an eye on the gloss finish, and if it starts to show signs of fading, you might consider getting it recoated to maintain its appearance and protection against heat and UV light.
