Volvo 780 with Cummins ISX

This whole restrictive air system isn’t that big a deal. Would it be better if it was bigger.... probably. Normal hp levels it’s ok. Especially with a good tunner. Under hood temps can be fixed with allittle hood trimming in a afternoon. Some of the positives about them is they are the nicest truck to drive. Not sure on pro star. But Volvo is roomy quite and comfortable. Cheap to buy. Mine has a squeaky dash that’s driving me crazy.... gona try and find that. If you wanna see a restriction in the intake. Take off the adapter pipe just infront of your air compressor intake on the manifold. Isx 2250. It’s pretty dumb how small it is. Half the adapter is plugged with casting and air compressor snorkel. Volvo charge cooler pipes are a lot smaller. But the intake it’s self is half agian smaller on the engine so take it for what it is I guess.
