Review: 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.

El paquete trae 6 bujías. Puedes comprarlo con confianza, son 100% genuinas. **Q: is this the correct size for a 2002 chevrolet trailblazer lt 4.2?** A: Most likely. The Trailblazer and the GMC Envoy have the same engine, and it fit the Envoy engine that I have. Be careful not to cross thread however. That is easy to do and anti-seize on the threads is highly recommended. **Q: Why this side say do not fit on my chevrolet trailblazer ltz 4.2 l6 year 2003?** A: 41-103 is CORRECT number for your vehicle. You can buy either iridium plugs (which is what I purchased in Oct 2017, and they still work fine) or you can buy the cheap original equipment plugs. But the 41-103 will work fine.
