Sparkplugs are OEM
The photo used is the original spark plug that came out of the truck for reference of how to assure your oem spark gap and acdelco oem number/code match. OEM fit for 2004 chevy colorado 4x4 z71 5.3l 5cylinder. Same as/match to the ones taken out - same acedelco oem numbers on label. Spark gap checked to oem gap.040 and refined in 3 spark plugs slightly placed off during shipping of package. Spark gap Guage as seen in photo is recommended in every spark plug placement at receiving of part and right before placement. If gap is not properly balanced in the cylinders it could cause loss/ potential power issues and also a Christmas light on the dash board/obd2 code. Recommended part with purchase if you don't have one already is a spark plug gap Guage. It is a general practice to every spark plug placement you can find one simply at your local Walmart for a fair price or order online. Auto part stores such as autozone, oriellys, and advance auto parts usually sell them a little more expensive. Best of luck and - God Bless

Prefect fit.
Bought these ACDelco 4#41-103 spark plugs for 2007 hummer h3. With 3.7L. These are a really good plug to buy for motors with higher mileage. You only need 5 of the plugs, cause its 5 cylinder engine. So you have a extra plug left.. takes a 5/8 deep socket. Make sure when putting new plugs in not to cross thread or tighten to tight.. also they are already pre-gapped.
