I've got a used but in very good condition K&N kit part # 57-3021-1 for sale. Fits 99-04 trucks with the 4.8/5.3, I do believe it will also fit 05-07 (07 "classic" body style) trucks as well too but don't quote me on that. As stated in excellent shape and the filter is brand new, purchased filter just about a month ago so it has maybe 500 miles on it at the most.

$110 plus shipping.

Will post up pics later today.

 

 

will this fit my 2003 Silverado ss??

 

Technically, no.

 

It should, I don't think there is any difference in air box to intake on your lq9 vs. a 4.8/5.3 of the same year.

If your interested, I would pick it up if it were me.

 

It can work with a little engineering thinking, as a matter of fact it was on my 2003 Silverado SS. But just like to be honest about the fact that K&N does list a different part # kit for the SS.

 

Ok, so what exactly would need to be done to make it work.....

 

Bump...

 

You would have to cut the intake box where the filter sits if you have the 34" radiator

 

I'll take the intake...sending pm now
