Better Mileage – This intake draws in more cold air resulting in a more efficient burning of gas due to increased air to fuel ratio running into the engine. Improve Engine Lifespan - Engines and radiators running on cold air intakes benefit from drawing in cold air as opposed to hotter temperature air. Saving Money – A reusable air filter is included in this kit. Re-washable air filters can last up to 100,000 miles whereas traditional paper filters need to be replaces every 15,000 miles.
