I was just thinking why the other brands cost so much more!
I bought this kit for my 2001 Chevy 2500hd 6.0. It took me 40 mins to install. It would have been faster if I wasnt putting it on outside at 15 degrees F. And if I thought to heat up the rubber fittings with heat gun sooner. I have been A K&N fan for awhile but I see no difference in quality with the Spector and half tne price. I am very Pleased with it Performance so far. I have noticed one mile Incease in fuel efficiency and love the sound under the hood when I stomp on it.
