Does anyone know what spark plugs i should get for my evo X MR. I was thinking about the M-Series HKS spark plugs. If anyone has an better ideas let me know?

 

How many miles are on your X MR that would warrant you to change out your iridium tipped spark plugs?

 

i have done 8000 miles but i was thinking as it's cold, for ignition response? Are you saying the stock ones are fine?

 

there is always better spark plugs then stock

i would like to know what are the BEST spark plugs to get as well

 

I think 8,000 miles a bit too early to change out the Iridiums. The iridums in my VIII saw 40+K miles before I switched it out. I actually had better gas mileage in the old worn out iridims then the regular NGK that are 3K miles old.

Believe it or not, but I went from 280 miles on full tank (mix city and high driving) to about 250.

 

i have some HKS M-Series spark plugs, but i'm waiting a little bit to put them in. i'm at 13,500+ miles currently, i'll probably wait until 15-17k.

 

What is the difference between the S series and the M series?

 

Stock plugs will suffice. We have cured a many customers ignition problems from using the wrong or aftermarket plug due to an internet fad that there is performance to be had with a "colder or high performance plug".
