Perrin's turbo inlet hose for the stock WRX and STi features 5-ply silicone construction with a wire mesh for maximum durability. Silicone construction means extreme resistance to heat soak, and a smooth internal passageway, unlike the corrugated rubber stock Subaru WRX & STi inlet.
This allows for freer and more air to enter the system ultimately creating more power. 2.4 inch on back order frequently please check with IIR sales rep if you need it quickly before ordering! Perrin's silicone construction ensures the maximum possible tube diameter is utilized, and the non-corrugated interior allows for optimal airflow; opening up the intake tract and making more power!
- New design includes a wire mesh reinforced silicone that resists collapsing.
- May require removal of intake manifold for installation.
- Will work with factory turbo

This product is well-made and will work great for your stock turbo, however if you have an upgraded turbo like myself it will not work for you
Great quality of the product itself. The fitment is extremely tight but I expected that with the larger diameter. Install is a little rough but that has to do with placement, not the product. Perrin definitely has quality products and this one is no exception.
I had originally bought the Cobb turbo inlet for my 2006 wrx but found that it couldn't come close to fitting under the power steering banjo bolt line. IIR worked with me and was quick to get the item refunded. After that I bought this Perrin inlet that actually seems to be designed to fit under that power steering line. Overall fitment of the Perrin inlet is also much much much better than Cobb's horrendously oversized inlet. Quality is great and install wasn't the worst (grab a buddy). Super happy with this part now and with IIR's customer service.
love this inlet. using on an FP green turbo. slightly rubs against the power steering banjo bolt
