My Current Plugs are Ac Delco MR44LTS6. Can i use MR44LTS or AC Delco 41-933?

 

AC Delco #41-993 is the replacement for the original 41-932. Both of those numbers are double platinum plugs.

 

cool, but my truck had the mr44lts6 plugs in it? what are those?

 

I cannot find any cross reference to that number...

I was able to cross reference to the AC Delco R44LTS6 which is a typical cheap resistor plug with a copper center electrode and a nickle coated ground strap. That plug will last 15-20k miles while the double platinum's will perform just as well and last 50-75k miles (realistically).

 

speaking of plugs I got number 1 and 5 out fairly efficiently but I am a littel stumped on number 3 the middle on the right side when facing the engine from the front grill. Would there be a special tool? Is there any suggestions on a special combo of socket, swivel, or extension? Thanks in advance, I have not even looked at the left side, LOL something tells me to be prepared for the worst LOL I pulled AC 41-932 so maybe this is the first plug replacement for the vehicle? Ouch 125K in miles, LOL I am replacing with autolite AP605 they were on sale $2 each, good stuff! By the way the discount auto in most areas is offering 5 quarts of oil and a purolator filter for $14.95 yes sir!!!

 

Check the Tech Article (DIY) section for information on the #3 plug removal.

As far as your choice of plugs, you will not get anywhere near that life out of those AP605's. I ran Autolite plugs in my Bonneville SSEi and was replacing them every 12k miles. Granted, that was 12k miles of VERY hard use on a supercharged engine, but a copper/nickle plug will last NO WHERE near as long as a double platinum like what was installed from the factory.

 

oh I see good point well I thought I was saving money but it sounds like a bad choice now LOL I dred having to change these plugs again, wow not fun at all!!!
