Review on High Performance K&N Cold Air Intake Kit: Boost Horsepower: Compatible with 2014-2018 Dodge Ram (2500, 3500) 6.4L V8, Part Number 77-1568KTK by Troy Larson

Revain installed incorrectly. Go to the K&N website and get the part number, then look it up here BEFORE you decide to order anything. Overall I wish they were cheaper but installation was very easy on my 2014 Ram 2500 Big Horn with a 6.4L Hemi. When accelerating from a standstill or downshifting, I immediately noticed a deeper growl. It may be wishful thinking, but I have a feeling it's speeding up. I'll have to report on the improvement in fuel economy later, it's too early to tell. UPDATE: After almost 3 months, my weekly gas costs have gone down. I used to spend at least $60 on gas, I only spent $15. The maximum I've paid is $35 and I haven't changed the driving routes. I love this product.
