This Cold Air Intake System (PDC8991CAI) is specifically designed for 1989 - 1991 Dodge Ram trucks with a 12V 5.9L Cummins engine. Most Pusher products are special orders and may take 2 - 3 weeks for delivery. Contact us for stock levels if you need it faster. The system features a huge Pusher 40CAL washable air filter and mandrel - bent 4' tubing. It has a very short path from the air filter to the turbo, delivering more air to your engine. It comes with a silicone coupler at the turbo connection with full stainless clamps and ties to the alternator for a stable connection. It works well with stock chargers, modified stock chargers, and S300 based chargers (use PN PDC9193CAI for S300 based chargers), as well as the stock exhaust manifold and aftermarket manifolds in the factory orientation. It's available in six standard colors and endless custom colors on request. Made in the USA.

Using this cold air intake system is easy. First, make sure your vehicle is turned off and cool. Then, carefully remove the old intake system and install this new one following the provided instructions. Pay attention to connecting the silicone coupler tightly at the turbo with the stainless clamps and tying it to the alternator securely. When it comes to maintenance, you can wash the Pusher 40CAL air filter regularly to keep it in good condition. This will help the system work at its best and get more air to your engine. If you need it sooner than the normal 2 - 3 weeks delivery time, don't forget to contact us to check the stock levels. Also, note that for S300 based chargers, you should use PN PDC9193CAI instead.
