Save your money. They add virtually nothing to performance on these trucks. Fact is, the factory intake is a cold air intake. Some aftermarket intake systems can actually decrease performance. The only thing you might notice is it sounds different (louder) when you press down on the accelerator. And for some people, this fools them into thinking it's faster.
I was gonna go with the new Mopar air ram but too much money so i found the Vararam Air Grabber. I think I might go with it after I get few more kms on the truck, Dont want any arguments about warranty. Already put a Magnaflow catback which has such nice sound. Need to lose the MDS cuz it sounds like ****. And really I am told it causes the engine to get poor oil flow because of the low revs all the time.
