So what are the results?

Gone is the rough engine idle, the "harsh engine shake" that I've been reporting about for a while now..

What's better? No more rough idle and harsh engine shake LOL..
AND! - the engine seems alot more quiet!

I don't know about any speed improvement but those problems above are long gone!

Lucky for the few people who had good results with the TM plugs, but my guess is that they are really more developed for american cars. You should see the owner's shop where the plugs are designed. It's filled with pictures of mustangs and camaros from the 70 and 80's racing. When I asked about Japanese engines, they weren't too informed about them. Maybe if they put a little more R & D into building TM plugs for the Japanese car market...

meZoom!

thats actually amazing....what your old plugs did. what did the firing pins look like/condition of the plugs?

It looked like they were all burning the same.

No more misfiring!

Lee,

Glad this fixed some of your problems. How about the shudder during acceleration? Any other problems still lingering around?

Again, thanks for sharing all your experiences recently. I have learned a great deal from you sharing the details and all the responses back from everyone.

Thanks
