## Questions & Answers

**Q: What size socket is need for removel and inserting these**
A: I believe a 5/8 spark plug socket.

**Q: Hola el anuncio dice 1 spark plug, no dice paquete de 6, en las respuestas dice que es un paquete de 6 bujias, porque no se específica en el anuncio?**
A: Hola! 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. 
Safe motoring
