The Truth About K&N Intakes
So Ive heard the good and bad about K&N products and thought that I would see for myself. So, I decided to buy the K&N intake and see what happens... How bad could it be? K&N is a trusted brand right? Im not going to bash them, but here is my personal experience: 5k miles ago, I spent all of my part time paycheck and bought one of these intake systems, spent a good 45 minutes installing it and was quite impressed when I was finished. Noticed better throttle response and a great open element turbo sound.
5k miles later now after checking/rechecking the intake every few hundred miles to make sure nothing had come loose/shifted and everything was solid, I decided to take a look at the turbo to get an idea of just how much dust and dirt this thing was letting in. I opened it up and was immediately shocked to see that the inner walls of the intake were caked with dirt!
This truck is my weekend driver/hauler and sees a slowly-driven dirt road once every other week (by itself and NOT driving behind somebody else who has kicked up a dirt-road-cloud). I had purchased a 6637 at the same time for fear that this might happen and have installed it immediately (still using the K&N intake pipe).
So for any other folks looking to upgrade their intake, I say forget the fancy intakes that go for several hundreds of dollars and look for the NAPA 6637... Cant be any worse than my K&N at only around $40.
Will upload photos when I can get to a computer.
