I'm wanting to find some spark plugs that are two heat ranges colder than stock to use w/ my turbo. The stock AC part number for my 3.4 is R43TSK. Is 43 the heat range? To go two ranges colder would it be a 41 or do the numbers drop off more for each heat range? Anyone know what the part number for plugs for my engine with two colder heat ranges would be?

Here is a pretty good topic.1997 GTP(13.3@104)-Sold<br />1999 Trans Am M6 -
Thanks. There was alot of information there, and branching from there. From what I may have been able to decipher I think a R42TS will fit my motor and is 1 heat range colder. I got some at autozone. They didn't have R41TS which I think are two heat ranges colder. Anyone know how to translate these to bosch platinum numbers? Also, what does the K mean in my stock R43TSK plugs? From what I found the R42TS and R41TS have the same dimensions as my stock plugs.Wayne<br />94 5 spd Camaro<br />Turbo/Intercooled<br /> <a href=\"http://www.geocities.com/Mustang732/cars.htm\" target=\"_blank\">http://www.geocities.com/Mustang732/cars.htm</a> <br /><br />Megasquirt Stand-alone EFI controling fuel/spark w/ wideband:<br /> <a href=\"http://home.att.net/~basic-4/2ndMegasquirt/NewMegasquirt.html\" target=\"_blank\">http://home.att.net/~basic-4/2ndMegasquirt/NewMegasquirt.html</a>Comment
