Autolites last as long for me as the NGK's. Either of them last about 10k miles for me. Any longer than that and I start getting missfires. The Autolites can be found for about $1.00 each

Pros: last 10k miles, cheap
Cons: misfires after 10k miles
Mileage: 10000 km

After changing the plugs from OEM's to Autolite 3923's, the coil packs started popping up. I've read that the Autolites are smaller than the OEM's, so they don't hold on as tight...and then somebody else said this is bogus and they're both the same. Whatever the reason, the coil packs on my car do not like the Autolites.

Cons: coil packs started popping

I bought some Autolite Platinums and now I find out they are crap Anyway, I needed something fast. Replaced them earlier this afternoon after work and so far so good. Acceleration is ALOT smoother.

Pros: acceleration is smoother
Cons: they are crap

Just installed my autolites 3922 (one range colder than stock 3923) they were gapped to 0.025" with this gap I'm having some problems on hot startups, colds ones are ok. I'll regap them tomorrow and see if it gets better, maybe I'm having some loss in performace as well due the small gap....

Pros: cold startups ok
Cons: problems on hot startups, potential performance loss
Part number: 3922

Last time I tried the 3922s and I was pleasently surprised with how smooth the car runs. I haven't had a misfire code since I changed over.

Pros: smooth car runs
Cons: no misfire code
Vehicle: Volkswagen
