Simple and easy to put on
Worked and was a perfect fit by external hoses to clamp. I’m sure you’ll figure that out in YouTube videos but definitely five star rating cleared my code.

Good part, fits 2007 Silverado classic 1500
It fits great on my 2007 Silverado classic 5.3L. The shipping on the part was 2 days later than advertised. Otherwise it seems like a quality part and the price is a lot cheaper than the local parts store. -1 star for the shipping.

Part is made in China.
On the box that this part came in it states that this part was made in China. When I was researching this part, I read that Fairwinds was an American company founded in 2017 in the USA so I mistakenly though the part I would receive was made in USA. I would not have ordered from this company if I had known the part was manufactured in China. So far it works. I hope it will last. Installation was easy if you can get the vehicle on a lift as I did.

Time Saver :Call Papa for the Extra Hand!
Worked, I noticed better acceleration and gas mileage!!! Just an FYI. What I did **If you have an old hair dryer or a low heat gun, you can carefully warm up the tubes and release them on each side gently so you can swap in the new part and reheat it back on with low heat. Then I added about 3-4 turns of electrical tape plus a hose clamp on the ends to secure. Looked clean and professional when it was assembled back on. It can be done! My Dad gave me a hand! If it wasn't for him, I would have spent too much time thinking it over. Thanks Dad! Love you!

The unit works and its essentially plug and play. I reset the check engine light and went for an hour drive with no issues. I'm not sure if it was placebo but i did feel a performance difference, albeit the old unit was FULL of dust and debris. if you're buying this for an 2003 gm with the unit above the tank, you can do it without lifting the bed but its a hassle. this unit wasnt a 1-1 match with the older one and i wasn't able to mount it in the same location but it might be a different story if you lift the bed. Everything considered I'm happy with the purchase.
