H&S Cold Air Intake kits are designed to feed more clean air into your diesel engine! Why is more air so important? The more air you can feed your diesel engine,the more power it will produce, and the more efficiently it will run. H&S Cold Air Intakes deliver unmatched flow and filtration, giving your diesel engine the most power AND efficiency possible. We don't just give you MORE air, we give you the coldest, densest, cleanest air charge that money can buy.
The computer-controlled diesel engines of today are much more complex than the coal-burners of old. No longer can you just toss any old filter on there and expect improved results. H&S Cold Air Intakes have been precisely engineered and bench tested for optimal flow and decreased air turbulence. We also optimally place the Mass Air Flow(MAF) to ensure you stay “check engine light” free.
