Here\u2019s where I\u2019m at after about a year of ownership. A few of these were just cosmetic fixes. I\u2019m at ~$540 total. Spark plugs, replaced with NGK BPR6ES - $20.00
Look good …. Just try to get denso or ngk
Switching fixed my ignition issues after having Autolite for only 2 days after purchase switched them to NGK and resolved my issues
Just swapped all four plugs in my 2013 Kia optima EX 2.4l for ngk iridium’s, still had the original sensor plugs in at 91k so honestly not sure how I didn’t have any misfires but have had a rough idle
Hondas are notoriously picky about the plugs being Denso.
I’ve used denso IK20TT in whiteblocks and they work very well, may need to re gap if you have some boost raising shenanigans going on
They are very picky with their spark plugs so you are limited to NGK which is oem.
I recently put in NGK LKAR7BIX-11S (93501) and some cheap amazon coils. A coil failed and I just replaced it all to be sure.
Put in NGK ILKAR7B11 (4912) around 186k miles. I've burned so much oil and did a piston soak at 205k~. I scrubbed the tips with a wire brush but it didn't do much. Lots of carbon. I really don't notice a difference.
I’ve kept to stock plugs with stage 1. I tried the recommended “colder” plugs and they failed in less than 10k miles.
I just changed out my sparks and found out the previous owners put these garbage plugs in it lol replaced with quality Iridium NGKs
