Airaid Air Intake System is a direct bolt-on replacement intake system available for 2004-2005 Buick Rainier 4.2L L6. This system is dyno-tested and tuned to properly extract maximum performance on each application. It provides a huge amount of cooler outside air into the engine to add additional +10 horsepower and 15 torque each wheel. A computer-designed CAD (Cold Air Dam) panels blocks hot air, protects the air filter from the engine compartment and helps provide free-flowing air under the hood. A huge air inlet tube is manufactured from mandrel-formed polyethylene tubing with black powder coat inside and out for durability. This tube is less affected by heat than steel or aluminum tubes. A 360-degree Airaid filter is the heart of this system and provides guaranteed 99% filtration. Made from non-woven synthetic materials with inner and outer wire mesh for superb filtration. Designed for everyday street driving, this non-oiled filter is easily washed and reusable. This system comes with mounting hardware and illustrated instructions. Made in the USA. Backed with Airaid's No-Hassle Lifetime Warranty!
