Spark plug Autolite or OEM BMW

I have autolite xp in the van. $100 for 6 ngk, $90 for denso with a van with 250k miles. Everyone says there crap, but it runs great.

I put Autolite Iridium plugs in my '06 N52 20k miles ago because of a crazy sale/rebate. It runs as smooth as a new one.

You're on the right track- replace those worn out plugs. Pre-detonation started on my '18 at 30k. Increasing octane rating to 93 worked up to 58k miles. $50 for a new set of [Autolite Iridium XP5363](https://www.amazon.com/dp/B078KWTCF2?ref=ppx_pop_mob_ap_share) resolved this problem.

Guy was gunna charge me $720 USD for changing my serp belt and another $550 USD for changing just my spark plugs. That's $20 for the serpantine/drive belt, $150 for the belt tensioner and I think another like $120ish for spark plugs (B58 engine). So in total I saved myself roughly $1,000 just doing it myself.

after changing the spark plug for another autolite it stopped misfiring its still a little rough so I fear it may comeback so I just ordered some NGK plugs.

I purchased some Autolite XP Iridium spark plugs earlier this month and immediately installed them. Within a mile of driving, the car started shaking violently and the check engine light came on. I immediately turned around and reinstalled the old plugs and the problems went away.

Autolite are pure trash maybe suitable for a lawn mower if you like breaking plugs off in heads

Autolites gotta be the worst fkn plugs on the market rn.

If you used auto lite spark plugs that is almost certain the problem.

autolites are some of the worst spark plugs, grab some NGK iridium’s and it should be fine
