B9 2.9TT/3.0T Spark Plug Failures? | 034Motorsport FAQ

These FAQ topics are excerpts from our live chats which we host weekly every Monday at 11AM PST. If you have a question to ask, join us in the next one or email us at [e-mail] and we'll happily answer your questions!
0:05: Have you guys tested out the slanted ground non-projected NGK r2558e-9 plugs for B9? I know it won’t help injector issues, but I am hoping it stops the grounds from melting/breaking off. Trying 810 today
2:01: I’ve seen a lot of B9 RS/S cars having issues with plugs. They are having to be replaced as early as 5k-8k miles. From what I hear, it’s an issue with the cars running lean. Have you guys looked into this to see if the tunes are creating these failures?
4:17: Are the failures happening more often on E? Or pump gas too? Or not enough data?

complaining about an extra minor service every 5k-8k miles after adding 250 more hp to your engine is crazy man 😂 probably the same type of dudes to complain about timing chain issues but then go to war arguing the point that it's fine to wait 5k-10k miles for an oil change on their modified german 😂😂

[@Slow4b9]

Seriously… no point in buying and modding this type of car without being willing to pay for the extra shit keep the damn car running perfect 🙃 buy an accord and slam it at that point

Should I replace an injector before it fails ? Every 10k miles. Plugs every 5K ? 🙃🥴🤔

[@headshotharry2313]

bro absolutely not, you shouldn't be replacing injectors.....On a tuned Audi I would change the plugs every 15-20k miles instead of the factory requests.
