Denso 3289 is what I run.
398k on the clock, like 50k on these plugs, she runs clean and smooth.
I just picked up 6 Bosch dual electrode double iridium spark plugs from autozone near me and threw them in. Fires great!
Denso for my runner
I used the gimmicky Bosch Platinum 4+ plugs which solved that problem (no more CELs) but sometimes idle is still a bit rough.
Denso or NGK. Buy them from a real vendor not eBay or Amazon or anything like that
I replaced the plugs with DENSO 5358 roughly 10K miles ago.
I also added bosch sparkplugs 4 months ago, and also have some stuttering.
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
BOSCH stopped German manufacture of spark plugs long ago, they suck now.
