I use a br8es plug in my 2002 R.. the br9es made it run like a sack of ****.

I know some imports use diff plugs think the 4dl used a br8 . not sure why something to do with sea levels and altitude or something along those lines ?

Have the same Iridium plug that's in the DTR, also in the 4DL engine in the hybrid, both seem to run well, cant remember if it's an 8 or a 9 off hand though.

I'm running the 4DL plug and it's a little lumpy to tell you the truth. I think the 4DL is the 9 and the dtr is the 8.

NEV is it okay to run the 8 with the tzr cylinder.

Dunno Cal, I have the Iridium plug in, the difference between the 8 and 9 is ones a hotter plug than the other, the 8 being the hotter plug IIRC. must say I'm big fan of iridium plugs, I have 6 in the Lexus, and that runs a treat on both LPG and petrol.

Im sure the br9es is cooler than the 8.

Yeah no idea why they did it that way round. Maybe there is a reason but i makes no sense to me. Feel free to delete these posts to clean up the thread though
