i got some from steve back in may i think, and they were like $12 apiece. car was quicker and smoother off the line. i couldn't be happier with them.

 

Thank you Uncle Dave!!!

 

Time to Chime in.

Almost ALL of us NOR CAL GS guys have had TM's for over a year. No one has had any problems that I know of. We all experienced some sense of power gain and several of us have raced our cars without any problems.

Off the Top of my head, those with TM's locally:

RedGS4
Jawnthen
Neo
TY328
Synergy
RMMGS4
Rominl ??

Comparing TM experiences of a Mazda Rotary with a Lexus V8 is apples to oranges.

 

Will these work on a GS 300 (V^)?

Seems as though most her ehave the 8 cyliner GS 400.

Thanks,

Ted

 

Thats Lexus GS 300 (V6).

Ted

 

Yes,
Neo and TY328 have GS300's using TM's.

 

Works fine.

 

What's the latest status on the Group buy?

Seems like we have a lot of interest.

Thanks,

Ted

 

First, this thread is REAL old.

Second, at least two members had constant mis-firing problems with TM plugs. A guy with a GS430 in Hawaii and myself (90 LS).

I actually went to the TM offices (friendly - yes definetly mom and pop - sorry to say but they aren't too up on newer engine systems) to have them check the plugs. They were sparking fine on the spark plug test machine but I was mis-firing all over the place. It could have been a gap issue but I'm not sure since I didn't get to adjust the gap before replacing them with TOYOTA OEM.

 

they come with the proper gap you cannot change it

I'm interested, but they need to work on their marketing materials - LOL
