Hi all !!!
Just went to Autozone to get Plugs for my '90 Deville 4.5L .
When I asked for part #R44LTS6 , they gave me R44LTSM and when I questioned it the employee said they were correct . So I want to ask here ,are they correct ?
Thanks for your replies.

I checked RockAuto.com and they specify R44LTS6 for your car.

Tip: Changing spark plugs is quite tedious on this car so you might think of installing longer lasting Platinum spark plugs such as ACDelco #41936.
