Is there much difference between these two engines? I found a spark plug that increased the gas mileage on my motorbike 10% and smoothed out idling and acceleration. It's called the Brisk spark plug and uses a 360° electrode design. I wanted to try them for my TSX, but they don't show the application for any TSX. They make the plug for the Accord 2.4L K24A3, but not the TSX K24Z3 engine. The NGK plug for both engines are the same. I spoke to the company rep about this and they said their plug for the Accord is not spec'd for my TSX. I think it should work if the NGK plugs are the same, but should I take the chance? They list all other Acura's other than the TSX. Is the K24Z3 engine used in other Hondas other than the Accord? MAGNUM Performance Spark Plug

Were the plugs on your motorcycle worn out when you replaced them?

There could be reasons why these plugs won't fit a TSX...but will fit an accord....even though the NGK part numbers for both are the same. It would be nice if you could get a response from an engineer there.

They may have just not tested the plugs on a TSX...or...there could be differences in engine compression, where the Accord can physically house a plug that protrudes into the cylinder further.

Is your TSX running rough or using excessive fuel?

Plugs were actually pretty new. Bike was running fine. These Brisk plugs were highly recommended to me by several bike owners in Europe who had the same results I described. I've been told the plug does extend a little further into the cylinder without any problems and the wrench size is slightly smaller than standard. You're right, this might present a problem for TSX engine. I've been in contact with their engineers they've said only for the Accord. You're right, they may not have tested it on the TSX. They're in Europe. The Euro Accord uses the K24Z3 engine also right? Not the A3. I'll continue talking to them.

My experience with Honda's and Toyota's make me skeptical in anything other than OEM spec'd plugs. The motor's don't tend to run right.

This statement also from that link you posted: Their lifespan is 25K mile - 40K km or 500-600 hours. Do they run that hot to have such a short life span? If so, is there any long term damage being done?

10% mpg increase can be controlled by your right foot. Smoother idling and acceleration can be controlled by higher quality gas. New 02 sensors could help with both problems too.

Not to be a debbie downer, but $18.00x4 / every 25k miles?

Seems to me like you've answered your own question and are only looking for someone to tell you it's OK to use them. Regardless of any advice you get here, if you try them and have a problem, you'll have no one but yourself to blame.

k24 z motors use a longer threaded plug, the will not work
