Review on Supercharge Your VW: K&N Cold Air Intake Kit for 2014-2016 Jetta, Jetta Gli, Passat 1.8/2.0L L4 - Boost Horsepower, Ultimate Performance Upgrade! by Kevin Swier

Purchased for 2015 VW Jetta TSI 1.8L Turbo. Installation was easy except for a few steps that weren't 100% clear, but you can figure it out with relative ease. It mentions cutting the air supply hose (if that applies to you), don't do 6 inches like it says. Shoot several inches at a time. If you make this mistake, it's best to reroute the air supply hose under the heat shield and it might be a stretch, but it's doable. This was the hardest part of the whole installation, figuring out how to reverse the instructions called. When you're done, the lights on the dashboard illuminate: a tire pressure warning light, a traction control light, and a general warning light. ). So if this happened to you and you didn't expect it, don't worry, you didn't do anything wrong. ON THE ROAD: a harsh sound, but not too loud to be heard. frequent and quite noisy I never noticed the stock exhaust valve until I installed and adjusted this intake. You will immediately notice an improvement in low-rpm torque. I didn't notice any improvement at high revs. It just helps the car lift and drive much better than the burst shot, but doesn't make all that much of a difference when you're trying to accelerate at higher speeds. In any case, I'm happy with it. To be honest I don't think it was worth $355 but I think I paid mostly for the name but that's just my opinion. Get one and see for yourself!
