I just installed an K&N Generation II filter kit. (basicallt the same as an Airaid) I found out you can rub a hole into the filter if it's not set up properly. I had to get a longer bolt and add about 8 small washers for the support bracket. The washers are used to make the bracket sit up higher. The filter will rub on the wiring harness which will create a hole. I fould if you loosen the O ring at the smaller silicone hose the adjustment works much better. If you have the red or a pinkish colored silicone hose you have the updated parts with your kit. If you have the black you can contact K&N and they should send you the new and improved. They are stiffer and support the filter better. Hope this helps. I went with the K&N over the Airaid because I was told by the parts store the Airaid will not pass Visual smog. I DON'T KNOW THIS FOR A FACT!!

 

I recently removed my filter to clean it and I was surprised to see a hole in my filter. It’s not a big hole and I don’t think it will cause any harm but I was surprised to see it.


I will try your method before I contact K&N,

Thanks again,

This was a problem with the first FIPK K&N came out with, only the hole got rubbed in the wiring harness. This is why many went with the Airaid setup. Thought that this was to have been addressed in the Gen II setup. Just a quick observation , this should have been posted in the Engines or Other Aftermarket forums.

 

Checked mine today and was starting to rub. Not all the way through and I will make some type of modification to make it sit up higher. Just wore through the fine metal mesh. You would think K&N would have better quality than this. I believe I will contact K&N about a new filter.

I contacted K&N through email. They sent me a new filter and the orange hoses. They did not ask any questions or want the other filter or hoses back.
