I am thinking about ordering a pro-guard 7 drop in replacement air filter from Geno, Garage.Any pros or cons,thanks for any Info.coobie

 

I installed one. I didn't notice a significant difference from stock, but I'm sure it is sucking more air. It will pay for itself....eventually.

 

Thanks for the info Mike coobie

 

Ditto what Mike said. Mine still sucks the filter minder down just like it did with the stock filter. The filters get dirty really quick so it's nice to be able to clean it, re-oil it, and reuse it. Just be sure to keep the stock one so you can swap them out in case the truck has to go to the dealer. Cummins doesn't like these filters...
