I did forget to mention $350 is for the Cool air Intake system not just filter. Wish I could have seen this before now since it kinda derailed a little
I added the AFE pro 7 on my then new 5.9 Dodge/Cummins. Biggest benefit has been a 70-90 degree drop in EGT temps while towing. Boy the AFE's are very expensive compared to what I gave for my new AFE back then. I've done a oil analysis every 50k miles and no issues with 300k+ miles on the odo.
