Owner reviews for spark plug

Just replaced my previously purchased NGK Iridium from Rockauto.com After 100k miles the looked like I put them in yesterday.

NGK Laser Iridium is the Honda spec and what I buy and have had no issues for 5x 105k intervals.

I did my AOS and water pump/thermostat, coolant change, trans fluid change, spark plugs and coils ( one failed while driving, engine ran horrible , but I was real close to home).

I read that NGK plugs already have a coating on them, so I didn't apply any when I fitted new NGK BKR6EQUP plugs. Torqued them to 25Nm.

The old ones (also NGK) came out easily and I used a bit of tubing to hold the plug as I installed it into the thread, making sure it was threaded on straight before switching to a ratchet and torque wrench to screw down and tighten.

I recently changed all the spark plugs and coils.

Every one of my internal combustion engines (3 cars, 2 motorcycles, zero turn mower, has NGK plugs.

Been using the cheaper Brisk brand and never had an issue for 20k miles.

The car works almost fine with the new bosch , i have a little vibration on idling .

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
