Plugs are by BOSCH. Post this job, it runs a lot better, and I mean a loooot!
if you want to save a bit and still want some quality get bosch plugs those are good too, I’ve used them before and they were pretty good as well.
Ran Autolite Iridum XP XP3922 plugs in it and had zero issues at about half the price of the NGK plugs, and I had a mild tune.
The bosch plugs can be found at autozone or O'Reilly's for about 18 bucks each. Cant recall the exact spec, but vw uses the Bosch plugs stock, so its a direct oe swap.
Also, some engines get particular about plugs. Bosch has a bad rep for the 3400 engine in my Grand Am, while NGK and AC Delco(I've got NGK Iridium IXs in there now) are fine.
Took original plugs out at 50K miles. Not awful but electrode partially rounded with increased gaps. Stock plugs are Bosch and apparently copper core, so I replaced with same. Recommended gap is 0.043'' Added anti-sieze to threads for easier removal next time.
Ever since Bosch moved spark plug production to Russia, the quality has been sketchy.
autolites are some of the worst spark plugs, grab some NGK iridium’s and it should be fine
I replaced my sparkplugs, and everything went smoothly except for the front plug on the driver's side. All the other spark plugs screwed in with little to no need for a socket wrench - except for tightening at the end.
This one plug seems to be stuck halfway down the middle of the thread and won't go deeper unless I really torque it. When I took the new spark plug out, I noticed that the tip was bent with the spark gap being much smaller than the other new piece.
I have a 2019 GTI with 65k km. I decided to do plugs and when I saw how expensive OEM were, I said screw that, i'm going to try the iridium auto value basic ones. I thought the difference in quality would be negligible. I ran the Autolite XP5325 plugs without gapping. All seemed fine but then when pulling on to highway under load at 3k + RPM, misfiring like crazy.
