Owner reviews for spark plug

I did not, and bought the Denso Iridiums. I have less misfires and slightly stronger gas mileage since install. Just my experience.

VAG engines seem to like their factory recommended Bosch plugs better than any other.

I used Bosch W4CS (cheap plug) with good results in my G60.

I run ngk bkr7e plugs gapped to .024 at 15psi. No probs here.

I have been runing the NGK BKR7E which is one step colder than stock (NGK Part# 6097) and I have a K04 with GIAC K04 software and other mods. They work great with a .028 gap. I change my plugs every 5K.

I just installed some of these NGK (BKR6E) plugs. I set the gap to .030 These went my 99 A4 1.8T Avant Quattro. The car is stock except for a K&N filter. Idle seems awesome and flawless all the way through the rev range.

I just replaced my plugs in an 89 16v yesterday. I ended up getting the Bosch platinum +2. I was leery of the platinums as everybody seems to knock them, but my car runs fine. They were 4 bucks each.

Been using the desno IK24's with a .32 gap. Works very well but that plug is a tad to cold. Runs a tad rough untill I get her warmed up.

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.

everything else runs pretty poorly on our cars. especially the bosch +4's
