Ignition coil Denso or HITACHI

HITACHI Ignition coil

If you do replace a coil, go with OEM or quality aftermarket parts. Cheap coils cause new problems. The Hitachi coils on RockAuto are probably alright.

Pros: quality aftermarket parts
Cons: cheap coils cause problems

I got the coil conversion kit from import car parts and GD 2.0l coils. The new age coils needed to be trimmed a little from the edges to fit. I bought hitachi coils instead of oem diamond ones and saved a lot of money. They work perfectly.

Pros: work perfectly, saved money
Cons: needed to be trimmed

If you go to Autozone and open the box of their 2004-2005 coil pack, IF it has a "Denso" or "Made in Japan" sticker on the bottom, it's 100% OEM.

Pros: 100% OEM if Denso
Vehicle: Honda S2000
