Spark plug NGK or Autolite

Rockauto has the plugs(NGK 97181)

If you’re tuned on stock turbos, OEM or NGK 97968s.

Im tuned and on an E85 mix but using 1 step colder NGK's (#ILZKBR7B8DG) gapped to about 0.022...needed these before I even went MHD though. Once I did most of my maintenance, the car required this for proper spark. Night and day of a difference.

I still put a small dab even though the NGK plugs recommend against it. I change my plugs every 15-20k because I have a tuned Focus ST. I already went through 3 sets of NGKs with no problems doing the small dab

I've had multiple Chevy engines that gave random misfire codes with autolite plugs- then ran fine on ngk.

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.

If you want relatively inexpensive and decent look up whatever NGK plug is correct for your car.

Yesterday my new Ariens made its maiden voyage up here in Maine and began misfiring under load. Called the dealer where I bought it and they said it may be the spark plug. Ariens apparently puts cheap Chinese plugs (Torch brand) in their machines. Long story short, new NGK and all is well. Powers through them berms like a pro.

Get those plugs out! I bought counterfeit NGK plugs from Amazon. By the time you get a misfire the ceramic may have cracked off around electrodes and damage your engine.

Definitely do NOT recommend Autolite spark plugs.
