Dual Quad Ram Air System
Add a dual quad ram air induction system to funnel fresh, cold air directly into your engine instead of the hot, underhood air coming through your radiator and off your exhaust. This system is a very cost-effective way to add up to 5% more HP, and it bolts on in minutes!

You’re losing HP!
Your open element air filter is feeding your engine hot air and costing you power and gas mileage. Get up to 5% more horsepower with a 5 minute bolt-on using the RamDuct™ Cold Air Intake system! There isn’t an easier performance upgrade that you could buy!
Don’t overpay for ram air!
Don’t pay $200 to $300 for the other ram air intake solutions. No need to cut holes in your core support or inner fenders, or relocate your battery. This is the best value you will find on a cold air intake that puts your hood scoop to work for you and looks good under the hood!
How much faster?
Car Craft Magazine lowered their E.T. by 0.29 seconds and increased trap speed by 4 MPH using a cold air intake on their project car. See “Mustang Cold-Air Induction”, Car Craft Magazine, July 2001.
Of course, your results may vary.
How much power will your engine gain? Boost your horsepower with a RamDuct(tm) Ram Air Intake now!
The RamDuct™ 2X4BBL Ram Air Intake restores or adds Ram Air to your classic vehicle with dual quad induction, working with your hood scoop to make more power. Automakers use cold air intakes on new cars to get more power and mileage, and now you can gain the same advantage by adding ram air to your dual carb induction systems. This is the most cost-effective way to connect your hood scoop to your dual quads, costing less than most air cleaners that don't provide any ram air functionality.
This version is for 8.5" carburetor spacing and up to a 21x10" air filter element, and is shown with a 1.75" tall seal. See the dimensions tab for more details. Other configurations may be available, contact us if you need a different configuration - we may add more based on customer requests.
The RamDuct 2X4BBL Ram Air Intake system is constructed from a high-impact resistant plastic that is paintable to match your engine. The base includes the seal, some adhesive to glue the seal ends together after any needed trimming and/ or test fitting, and two air cleaner/carb mounting gaskets so you just add your existing air filter and lid. The complete assembly comes with an oval filter, lid, and mounting hardware - everything you need to install it.
