Spark plug Bosch or Autolite

I've used Autolite plugs in the 2.0's I've owned for over 20 years now because I think they work the best of the ones I've tried with this engine.

The new ignition switch is in. The spark plug wires are Bosch copper and now have the Bosch super 3 ground electrode plugs installed. So with a fresh ignition switch that eliminated the odd electrical changes we were seeing in the dash lights, now stronger cranking and it does run better.

I would also like to leave a comment here about having success with an autolite AR52 plug. Same exact thread size and identical reach as the OEM torch plug.

Bosch W6DPO. They’ve always been expensive, but now stupidly so. I’m not paying $250 for plugs, either. The DENSO IW20TT you referenced is a perfect replacement because it’s the exact same heat range as the W6DPO.

Bought mine from rock auto; got the Bosch ones since the NGK’s are really only recommended if your car is tuned

I bought some Autolite double platinum spark plugs because they were on sale at the Napa where I live but everybody I have tried asking to help me do my spark plugs has gawked as soon as I say "Autolite" and tells me that I'll have nothing but issues with those plugs and that "they're only good for Fords" basically.

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.

I replaced mine with Bosch once, it drove like shit and I immediately replaced them with NGK.

I put the expensive double spark, spark plugs into a Mitsubishi galant one time. Plugs were supposed to be hotter and make the car run better, after a couple weeks I swapped them back out for nkg’s that I checked the gap on, car ran better.

Never use bosch plugs. I work in a bosch car service and we won't use em, NGK only. Bosch stuff is garbage
