Install on 7.4 engine 1997 2500 Chevy
Unit came with everything to install. Had issue with the silicone sleeves not being the stated lengths. Had to cut.The bolt size was changed to 3/8's from 5/16's on the air box which would not allow the supplied washers to be used. They need to look at that issue. Over all the final fit and apperance is good.
2004 S-10 Blazer, 4.3 Multi port (4dr-4wd)
The Cold Air kit was really simple to install. Took about 15 min. Went right on with no problems,great fit. You can feel the change as soon as you step on the gas. Smooth effortless acceleration. My gas milage seems to be around 20 hwy and 17 city. Acceptable enough for a car that weighs 5387#.
