Had a boost leak off the stock inlet replaced it and the o ring gasket and problem solved love this would definitely buy again ps you may have to cut it a bit if you have aftermarket intake
This product is amassing. For sure it help a lot in the performance. If you want 15 hp more get one of this hose.
Comparing this part to the stock inlet , you can see alot of restriction from the stock piece. I installed this paired with the Perrin cold air intake, Perrin charge pipe , grimspeed ebcs and boomba bypass valve. You may have to play around with the alignment of everything so dont tighten down all your clamps right away. It wasnt very compatible with the grimspeed ebcs but you can take 5 minutes and make it work. Make sure you have some extra vaccum lines and fittings if you're using the grimspeed ebcs.
This is product eliminate the restriction on my inlet due to the stock one and also make power delivery much smoother.
Another well made piece by Perrin. I didn’t really like cutting up a part that’s close to $300 but in the end it’s a lot nicer and more durable than the OEM turbo inlet.
