Problems with K&N Air Filter
Click image for more information
More than a year ago, I decided to remove the AirAid adapter and K&N filter and go back to the factory air box and filter. A local Jeeper offered to buy it as he needed it for some project. Anyway, it is now history. I had read enough reports and from personal experience, saw the amount of dust that an unprotected K&N filter was letting through (hence the filter bag on the K&N).
Today, I was doing a tune up on the TJ. I was near the 66K mile mark and thought it would be a good idea to do some maintenance on the ignition components and clean up the throttle body a bit.
I had never bothered to check the other end of the factory air tube when I had discovered the dust getting through the K&N filter. The above pic shows the remains of the dust that had accumulated in the air tube from the K&N.
You know, it is pretty bad when the inside of the air tube is dirtier than the outside. Enough said......
