Spark plug NGK or Autolite

Ive used denso iridium and now use ngk iridium. Both have worked very well and last an eternity....as long as the car is properly tuned. A lil more expensive but you dont have to touched them as often as copper plugs.

ive been using NGK plugs in everything from my motorcycles, to cars, to outboard motors, whatever.. ive never had a problem with them.

BKR7E at .028 on a 2871R. I change them every oil change so basically ever 3k miles. For 9 bucks you can't go wrong. It's like instant power back. I have noticed though sometimes when I change them that the gap has opened up.

recently put in some NGK BKR7Es and so far so good, gapped at .026" (or .027 i can't remember and im not taking them out to check )... ran it up to 20psi and it seemed to run harder

I use BKR7E .022, I change them every 3000 miles...until now no issues..and they are cheap

brk7e's are excellent...2.5 years with no issues on this particular plug(not the same set obviously). .025 is a good gap, alot run .028..but i have found. 025 to be better,especially for frequent WOT driving in the heat here.

first set i used were NGK R5671A-7 non-resistor plugs gapped at .025\" had ran multiple sets of these for well over 20k miles with zero issues.

I'm flashed with Revo Stage 1 and I run NGK BKR7E plugs gapped to 0.028\". They are 1 range colder and are cheap ($15 for 4 at Lordco if you have a discount). Only downside is that you should regap them every oil change, and change them ever other oil change

I went out bought the NGK plugs and installed them moments ago. Reset the codes and started the engine. Within 1 minute I had the CEL and the P0351 - P0354 codes.

I got some NGK DCPR8EIX's and gapped them to .022" and took them for a drive and they were fine. Then this morning on the way to work I did a 2-3 gear pull and got some misfires after my 2-3 shift.
