Got my K&N installed over the weekend. I noticed a bit of a performance increase and definitely a MPG boost. Driving expressway from South Bend to East Lansing average about 70-75mph, I got around 17mpg. Normally I would've gotten 15, so I was impressed with that. My biggest complaint is that the air box doesn't fit up against the fender. Here are some pictures.Mindi

Looks good, glad to hear you noticed an increase in gas mileage. Always good for the pocket. And maybe you can get an extension from the air flow sensor to the tube? Just get a longer piece of the rubber.

If the sides went all the way to the fender could you get enough air flow through just that hole on the fender. It doesn't look like it would provide the necessary air flow.BRYAN

Ive installed a few intakes in the past and if i remember right they always fit snug up against the fender. even at that the rubber seal makes it look like it is sapposed to be up against the fender. I am building my own intake for my truck and im not going to have a air box for a while.

I had 96 Suburban which used same kit and it did fit against the inside fender. I would call K&N tech line.

Hey MIndi, Ive be looking at your pictures and I havent figuired it out yet but it looks like a part is missing on the intake tube. It been a few years since Ive worked on 96-99 trucks. If I figuire it out I will post.
