It's hard to go wrong with NGK spark plugs on Japanese vehicles. That's what I've always done with great luck.
I'd recommend getting either spark plug yourself at a parts store, they last much longer than platinum spark plugs and offer more performance. plus the rutheniums, if available for your model year, offer slightly better fuel economy as well. if you want the ones with the longest longevity and best performance I'd get iridium high ignitability, but those can be costly. definitely go with NGK. bosch are also decent and denso are usually oem but I personally prefer ngk.
I put NGK B5HS plugs in mine, no complaints so far.
Torch F7tc took 3-5 attempts to crank. This NGK paired w my Wgen11500 cranks first try every time. Very pleased.
RX7 mark 1. Wouldn't rev past 6000 with Champions, replaced with NGK and sang like an angel. It's not the price, it's the quality.
Go NGK and Iridium. They are a better spark and help burn any sediment off the tip. Also bonus is, they last about 50-80,000km.
If you do get plugs, go with NGK plugs instead. Good quality.
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
Just replaced the OEM ones with the NGK PLFER7A8EG 94833 as part of my 40k service on the car. Pretty straightforward like usual except the hard part is maneuvering the coil pack connectors that rest again the intake pipe because of the plastic covering that thing was such a pita. But now the car feels like heavy, like when you put on some heavy wheels on and you can tell the difference right away. I've been having to be so light in the gas pedal because it would fly. Now it feels like I really have to push the pedal a lil harder then usual to pick up speed but it just feels heavy kind of (not sure it's the best description) but it's it not hesitating at all.
I replaced the spark plugs with NGK Iridium IX factory gapped to .044". Everything went smoothly, reinstalled coils, air box, battery, connected MAF, and started the car. Now it is shaking, smoke coming out the exhaust, and blinking check engine light.
