garranteed more air , jus take off the flap that switches from grill to fender and it will take air from both . should be better response . Plus a better sound . Cant get any worst than what it is now , if anything should be better . Let me know how yours goes .
Where is the guarantee?? Where is the PROOF? "SHOULD" be better response??
What do you consider "worse than it is now"?? :confused013:
Have you actually done a research, not Joe Blows "hear say", or an advertisement for the product by it's manufacturer?? At one time there were several researches done by non-bias research laboratories not only with the Cummins OEM air filter but also the Chevy D/A OEM air filter...and it was REALLY, REALLY an endeavor by these after market "cold air intake" air filters to not only allow MORE air flow, but also to keep more contaminants out of the intake than the OEM air filter. Sure, the OEM air filter doesn't have a "fancy shape" or "pretty color" and may not be packaged the same, but any gain is mostly hype...I guess if one wants to pay several hundreds of dollars to just think the sound of the engine "might" change a little seems like a waste of money to me, but as many of you will now say, "It's my money", you're right, but it's been proven there is no where near a significant gain of anything to merit the cost. May have helped older trucks, but this IS a 2013 forum and clear back to 08' it was starting to be proven that the K&N oil type filter was a bad idea on a diesel engine, (MAF sensor being biggest issue), but I've done the research and not bought into all the hype that the manufacturers of these air filters plaster all over the place about their merits....really isn't there...
heck, you want noise, drill a hole in one of the headers:thumbsup:
