Spark plug Autolite or BERU

I use Beru Utra-X UXF79 4 tips plugs. It's a great plug for my chipped B6.

The cheapo Autolite 3923 works very, very well. Works well with chipped and K04 cars also.

i run autolite 63 (gap to 24 thousandths) on my stage 4 for 500 miles with nitrous, they look perfect. 99 cents each. to each his own.

It has been satisfactorily argued that the inexpensive Autolites work as well as the expensive Iridiums, with the understanding that the Autolites must be changed more often.

I have autolites, they work well, but the car became jerky at part throttle when gapped at .024, runs better when opened wider for some reason.

Autolite made the only plug I've ever had that was dead when brand new.

I did the plug change for the first time on my Tig. Pretty easy and took maybe 30 minutes. tricky part was getting the wire harness/clips to release from coil packs. Just be patient and use a small screwdriver. FWiW, I used Autolite Iridium plugs cuz my local NAPA dealer was out of the NGK's and recommended these. The quality was really bad on my set.. The cathode (curved portion of the plug) was significantly off axis, misaligned. One plug was bad enough that I returned it for an exchange. These plugs get high reviews on Amazon, so I kept them in without any problem but will be going back to the OEM NGK's next time. My old plugs looked very good for 45K miles.

I didn't know any better and used ****ty autolite spark plugs, and everything was fine and the misfires went away... A few days ago I noticed on quick acceleration and around 4-5k RPM's, the engine loses power, accelerates slower than...well, slower than a 2.0 normally is.

The autolite is a cheap plug, not what is recommended to be used.

Don't put autolite (autocrap) in your car, they're junk.
