I am about to change my spark plugs on my 2011 V6 mustang. Anyone one know who makes the best plugs for that engine.

 

You already have 100,000 miles on your 2011 mustang. Holy good god. I only have 25k on my 2011. Lol. Napa makes really good spark plugs. Napa sells awesome platinum plugs thats good for like 150,000 miles.

 

No I only have 56,000 but was told at dealership that at 60,000 they need to be replaced.

 

Oh, Heck no bro. The stealership is trying to jack you for a tune up. Our spark plugs are good for a minimum of 100,000 miles but here don't take my word. Lol. Here is a copy of the scheduled recommended maintance for our 2011 Mustang which was put out by the Ford Motor Corporation. Look at 100,000 miles:





Your service department is looking to take your wallet for a ride. They are trying to hit you deep and dry with no lubrication. Straight up gang bang my poor brother here. Lmao.

 

NAPA doesn't make any spark plugs, sells all major brands though.

Platinum plugs are only good for about 60K to 80K, you should only use iridium spark plugs in late model Mustangs.

If you are going to change them then my recommendation is NGK iridiums.

 

Sorry. Your right. I meant radium spark plugs and they don't need to be changed until 100k the factory ones

 

Thanks for the info! That was my first and last time at that dealership!
