I just picked up 6 Bosch dual electrode double iridium spark plugs from autozone near me and threw them in. Fires great!
I used the gimmicky Bosch Platinum 4+ plugs which solved that problem (no more CELs) but sometimes idle is still a bit rough.
I run Champion plugs in my Harleys. I have never had an issue with them and when I did try others, I never noticed any improvement over the Champions.
I got a sp series cold air intake and ecs performance ignition coils with bosch spark plugs. I once ran this car with 3 spark plugs for to much time and almost no oil at one point too.
buy original. or atleast bosch, they are OEM-quality
these BRISK ones are cat in a bag
I also added bosch sparkplugs 4 months ago, and also have some stuttering.
Some of my best vehicle purchases have been trucks with "misfires" or "engine issues" and almost all of those have had goddamn champion plugs in them, or a champion distributor.
But let this be a lesson never use champion plugs again
I replaced mine with Bosch once, it drove like shit and I immediately replaced them with NGK.
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.
