Review on 💨 High Performance K&N Cold Air Intake Kit: Increase Horsepower for 1988-1995 Chevy/GMC (C1500, C2500, C3500, K1500, K2500, K3500, Tahoe, Blazer) 5.0/5.7/7.4L V8, Model 63-1007-1 by Richard Lamptey

I have a 1988 Suburban 350 that I have fitted this item to. I get about 1.5-2mpg when towing. I went from 8mpg to 9.5 or 10mpg. This forces the engine to work on long climbs on very steep slopes. I think it's because it's not a cool intake system. Draws in hot air from the engine compartment. Whether the mileage in the city has increased without my 28-foot trailer is still questionable. But I think I scored maybe 10%. Would I buy it again? YES SIR. Although I lost power while towing in the mountains, it's worth the extra mileage.
