Purchased for my 2001 HO 24 valve Cummins 6 speed Ram 2500. I forgot to check about gaskets. Were none with spacer. I saved the old gaskets during removal and put a little Black RTV gasket maker with old gaskets. Worked fine. Happy with product. Fit perfect, looks good. I installed this along with a boost elbow and a boost fooler on a stock truck. I also installed a 4 inch turbo back Magnaflow exhaust. I pull a 13000 lb fifth wheel RV. I believe the heater delete spacer added a little more grunt down low. I have no tuner on this truck, its box stock and it pulls like a freight train. Good fuel milage also. Leave the twin solenoids in place and connected to control wiring.Remove power supply cable from battery to solenoids. Also from solenoids to heaters. No idiot lights this way. Install took me about 15 mins.Easy to reinstall if needed. Truck starts with no issues.

I picked this up from XDP at the Diesel Nationals in Indy, and this is by far the simplest and easiest mod I have ever done to my truck. Not only does it dress up the engine bay a little bit on my 24valve, but it eliminates the restrictive heater grid and reduces turbulance of the air coming into the engine. It's hard to notice the increased "half pound of boost" but I have noticed a faster spool up. This thing is awesome, and definitely worth the $60!! Keep up the great work guys!

Most Popular Questions

This part will work with my 2003 Dodge 3500 cummins? My truck will not start unless it is plugged in. When I checked the grid heater, there is very little warm air pumping through the unit. Will this XDP part work to replace the Grid Heater?

How well does it work in cold weather?
View Staff Answer 
This product is not designed to be used during the cold weather seasons. It's recommended that you remove the intake heater grid delete and reinstall your factory heater grid once the cold weather begins to ensure reliable starting in cooler temperatures.
Would the check engine light come on? Engine code
View Staff Answer 

When installing the XDP INTAKE HEATER GRID DELETE XD126 you will want to remove the wiring from the solenoid to the heater and the wire from the battery to the solenoid. You may get a soft code stored in the computer for low heater grid voltage but this will not set off the check engine light (CEL).
