What are the best Spark Plugs for a 2008 Mitsubishi Outlander XLS V6?

 

i think rbg or something.. not too sure.. i'd like to know this as well.. lol

 

NGK ILKR7B8 are supposedly OEM plugs...Rockauto has them for about $10 a pop. I'm reading into how to change the back ones. looks like the upper intake plenum comes off.

 

Are those top of the line?

 

I tried Bosch Customer service they said they only have plugs for the V4

 

I think I am going to go with these Denso automotive parts available online at DensoProducts.com

How long do the spark plugs last in a 2008 Outlander XLS v-6?

 

i just replaced mine at 105k miles. they still worked relatively well, but my butt dyno notices a difference. I haven't seen much of a MPG difference yet, but the engine feels more solid/confident...better accelerations.

I replaced mine with NGKs, same model.

 

What is better NGK
or Denso-Spark Plugs

 

no clue...NGKs are OEM, which is why I put them back in. Pay close attention to part numbers to get the right plug.
