Spark Plug Interval

K20-HUR11 for me.. cheap and readily available. My Tacoma really didn't like iridium for whatever reason and ran like crap when I tried them a few years ago.

V6 only took me 10-15 minutes at most. And most of it was me sitting there checking the gaps/comparing with new and taking pictures of the old ones.

I posted this picture before but here's a 100,000+ mile plug with a gap of .061-.063...

 

Appreciate the link to the quick reference guide, that's going to be very helpful in the future!

 

Nice! Gaps like those are exactly how ignition coils burn out and go defective early. I'm not giving you a hard time about your post BTW (but I could, lol).

 

No worries, just a learning moment for anyone that stumbles across this thread!

I beat myself up already lol I practically refreshed my entire truck and saw the spark plugs in my Amazon list... Way at the bottom probably the easiest maintenance item that can be done too...

 

Just changed the copper plugs. 30K interval, 120K on the 4.0L. They looked great. Cheap and easy to replace. Good time to clean the throttle body and maf sensor.
