Pretty much as advertised

It was harder to install than advertised. The fit was very close, but still a bit difficult to make fit - the tube was just a hair too long and not bent to quite the exact angles needed. The rubber grommet supplied for the sensor kept sliding inside the tube during installation. It took me about 5 tries to get it in. I finally had to put the sensor into the grommet, and then force it in to the opening one bit at a time using a flathead screwdriver. Oh yes, I coated the bottom of the grommet with Vaseline too.
Even given these issues, I am very happy with the resulting improvements in sound, performance AND gas mileage.
The truck sounds great (I had already added a cat-back dual exhaust system on the truck). Installing this gave the truck a deeper, throatier sound - more like a performance vehicle.
The greatest improvement in performance seems to be in accelerator response. The low end torque seems much improved. It is now far too easy to chirp the tires if accelerating hard from a stop. I live near a Highway Patrol post. I have to be careful. :O)
I am most pleased, however, with the improvement in gas mileage. I estimate 2-3 more mpg. I haven't measured it exactly yet, but this is my daily driver and I am using far less gas than before.
Oh yes, the pictures in the installation guide were very poor quality.
Over all, I am happy with the product, but the fitment and instructions could be improved. I would recommend this product to others.
Pros: easy to install take your time read directions and it will fit reset amd move sensor running over top or will scratch
Cons: none you will fill and hear difference at start up buy this not K&N save $$$$ same product
this was so easy to do just take time follow directions the effects are awesome and the results in fuel will follow if you keep your foot out of it if you want more add a magna flow muffler for more sound and savings I have a 4.8 sierra went from 13 to 16.8 mpg!!!!!!!!!!!!! and I think it can be better with new plugs Also Magna flow to me sounds better than flow master
