Spark plug Denso or OEM Honda

DENSO ZXE24HLR7 is also an excellent OE plug.

Denso 3289 is what I run.

398k on the clock, like 50k on these plugs, she runs clean and smooth.

Denso for my runner

Denso or NGK. Buy them from a real vendor not eBay or Amazon or anything like that

Replace with OEM - Denso. And yeah, get them from rock auto. Anywhere else is way too expensive and eBay is most likely counterfeit garbage.

OEM are actually cheaper than a lot of aftermarket plugs. Buy from a place like bell Lexus or just get the denso branded equivalent. They last hundreds of thousands of miles in some cases, so OE has certainly proved its worth

Denso 3297 on Rockauto are the Oem plugs

2004 1.4 Jazz. 225.000 kms approximately. It is OK but the idling is poor (having done a valve clearance and changed spark plugs and coils). Meh…..it is still holding so I’m hoping for 100.000 kms more

definitely not ok, they are spent, also Denso>NgK any day of the week

The previous owner had installed some Denso IKH24's that looked..... disgusting. In fact, I have NO CLUE how the car ran as well as it did, as the tips from the Denso plugs were gone, and the gap was 0.055. The car still had a slight miss after I did the coils last month which prompted me to replace the plugs.
