spark plug iridium

[7138]

pinalitan kasi nang Honda cainta nang stock lang... ngayon nagkakaproblem ako sa pugak pugak.

Kailangan daw ibalik sa iridium sabi naman nang greenhills.

i disagree with this, sa owners manual natin ang nakaindicate lang dun is yung regular plugs lang ng NGK and denso,
my car too is a honda jazz, and currently it uses regular plugs. wala naman pugak.

been reading fitfreak.com for a long time and ang usual suspect sa kanila kapag ganyan is yung coil packs.
have it checked.
