K&N Cold Air Intake Replacement Filters

replacement filter and k&n cold air intake 63 series

Very happy with the replacement filter. Even more happy with my 63 series k&n CAI on my impala ss. I went from 18.5 average fuel economy to 20.4 average fuel economy. 21.0 on the highway. Sounds nice and love the look. I will for sure buy these products again and only from autoanything. One year price guarantee can't beat it!!! View more reviews...

2003 GMC Sierra
Edge Insight CS2 Monitor

Small, but still very easy to read.

Super easy install. The device is tiny but still really easy to read. Tons of information. View more reviews...

2016 GMC Sierra
K&N DryCharger Air Filter Wrap

Works good!

I was happy with the fitment and quality of the filter wrap. A little spendy at almost 40$ but it will save me when i take the truck out in the sand or water. Not very impressed with the "overnight" shipping but i can't complain too much because it was free! Would buy again despite previous purchases that went bad with this website. View more reviews...
