The boost tubes are a weak link between the turbos and the intake as theyre restrictive. The k&n set up is super solid as obviously k&n is a proven name, but imo it fits better on the gen 3 than the AMS did ones on the gen 2 due to tightness.
The COBB intake is my favorjte CAI. You wont gain 100 horsepower off it. The main benefit is a larger filter, slightly more turbo noise, and some bling under the hood by an awesome company based out of Texas.
I run both. As does Winfield. I think theyre super solid in all honesty and help you keep a slightly cooler temp. But overall its mostly turbo noise and they can be tuned to get a few horsepower off of it. Winfield would be exact figures but maybe 15 if I had to guess? Shoot me a message if youd like and Ill bundle price them together. Ill also link them separately below.
This part is legal under the provisions of EPA’s Anti-Tampering Policy. COBB Tuning has established a reasonable basis (testing results) via SEMA Garage Emissions Certification that verifies that this product allows the vehicle to operate within legal emissions standards and is therefore legal...
Turns out I need to create a website profile for the k&n boost tubes but Ill work on that tonight.
Gen 3 here. I have the Full-Race intercooler. It came with some hard pipes, but not all of them. I have a couple of K&N ones to make up the rest of the system. I also run the COBB carbon fiber intake and it all works together. The Full-Race tubes are down under. K&N tubes up top. Edited to add pictures.
