FaradMk4 0 Posted January 8, 2017 Report Share Posted January 8, 2017 I'm about to perform a tune up to my 2003 Jetta Gli. I was wondering specifically, which sparks plugs you guys are using for Daily driver use. My car, motor wise is stock. I also plan to upgrade the coil pack and found a set at ECS tuning. Any tips, direction and advice would be much appreciated. Thanks in advance. Link to post Share on other sites
markcunningham 0 Posted January 8, 2017 Report Share Posted January 8, 2017 NGK's are a good pick. Just search your car for spark plugs for that engine and get NGK. Link to post Share on other sites

Assuming you have a VR6 V6 Edited January 8, 2017 by markcunningham Link to post Share on other sites
FaradMk4 0 Posted January 9, 2017 Author Report Share Posted January 9, 2017 Thanks mark. Yes I have the VR6. I am currently using the NGK spark plugs, I was wondering too because I heard Bosch was good for our cars too. Link to post Share on other sites
