This was awesome. From the ordering and quickly shipped process, to the clear installation instructions, it was easy. The booklet said 1.5 hours start to finish and it only took @ 70 minutes. What a difference it has made. K&N claims a modest gain of @ 9 hp (I think) but it feels more like 20. I also put on a dual Magnaflow cat-back system 2 days prior. I have a 2002 GMC EC 4x4 with a 5.3L v8. Wonderful and highly recommended. Hal
