I purchased this for my 2003 Envoy XL 4.2L V6 for towing mostly. I also have a K+N cold air intake. My wife and I have noticed a difference in shifting gears, lower RPM's in regular driving and towing, more power where it needs to be, but have not seen a drastic change in fuel economy. Have only had it installed now for 3 weeks. I would certainly recommend this to anyone.

I looked at a few other types. Glad I got this as it fits perfectly below my radio and the Adjustable light/color setting are terrific. Also having it automatically go on/off, removes the Possible battery issuer. Haven't tried all functions, sure they will be good. Check reviews of all items before you buy. It really helped steer Me to this product.
