Owner reviews for spark plug

NGK OEM equivalents or Denso IK22 for a slight bump in performance.

I've always used NGK plugs on my Hondas. My 2nd generation Fit I installed NGK Laser Iridium.

Bosch Plugs are tops in any application you use them for... All of their parts are worth what you pay for them...I've...\"NEVER\" had a Bosch part of any kind to fail at its applied usage...! True top of the line German Engineering... period...!!!!!!

I went with NGK. Been great so far (been about 2k miles).

I used Bosch plugs in mine about 3 months ago and I couldn't be happier.

You only need 4 so might as well go spark plugs that Nissan GTR uses

I’m running Denso plugs in my car…no issues to report.

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.

Champion aren't a great brand. They may have been at one point, but not any more.

BEWARE O’REILLY’S AUTO PARTS CHAMPION SPARK PLUGS ARE WEAK AND BREAK AT THREADS AFTER HAND TIGHTENING AND THEN TIGHTENING NOT EVEN A QUARTER INCH OF A TURN, WAY BEFORE THE TORQUE SPEC AND THEY TWIST RIGHT OFF N BREAK.
