You should have replaced valve cover seal too. Itâs pretty easy to do and not too expensive if you opt for OEM. Not replacing it will cause your new spark plugs to get drenched real soon.
Itâs a pretty common issue with aged L12A2s and L15As found in PKDM Honda City.
Which plugs did you use? You should only use iridium spark plugs. I donât remember the exact specs but follow it. My replacement motor had still original in it. So, I never replaced them.
9/10 kpl with AC in city is good enough. Proper tuneup, valve clearance adjustment could give you a 1~2 kpl more.
