2001 PS190 LTR330 Running BAD!

[jmac197]

$1.99

my manual states that the '02 LTR requires the MR43LTST. Note the extra T on the end of the part number. What does that extra T stand for? Can I use the MR43LTS?

The NAPA guy looked in the front of the book and thought that it meant that the plug was for a tapered seat. Make sense?

Thanks
Jim

I don't remember the tapered seat, but I believe the last T is referring to that. Call MC to verify this.

Message Engine Nut and he can let you know if your engine can run the LTS plugs.

That extra T at the end of the number must be an error. I checked the MR43LTS plugs in out stock and they have tapered seats. They are the correct plugs for all LT1's and 5.7's with Vortec Heads.
