its about that time for the spark plugs to be replaced so i figured i would put some better ones in, just wanted some suggestions for which ones to use

 

im using the Denso Iridium plugs, i think they are model # IK16..i might be wrong tho. They seem to be working great. they're kind of expensive tho.

 

I have the NGK Iridiums (www.optauto.com should list the correct model). They have been fine for 2,000 miles so far.

 

I also use NGK Iridium, that's great.

 

I've had my NGK's for just over 7000 miles and love them. I've heard good things about denso but they are expencive.

 

NGK all the way, cheap and do the job

 

Iridium . . . I'm not big on them, unless forced induction + NOS + very aggressive timing.

 

What about Bosh Plat 4's?

 

Exacly what I was about to ask... What about Bosh plugs

 

The mitsu dealer recommended ngks or densos (they come with cheapy ngk plugs stock) he did not recommend bosch but i have teh platinums (not +4) and they have been fine for me.

 

i just got some denso's... i've yet to put them in... sorry about the off topic comment.. but... do i have to adjust the gap? and if so, what's the correct gap for the lancer?

 

If you got the model listed for the Lancer specifically, they are already gapped. If not, you need to gap them.

 

This is my experience with my car, even though it is not a "Lancer" per se.

Bosch Plats after a couple hundred miles, started fouling up and misfiring. Yep, they were gapped properly. NGK has been my plug of choice and I have had no problems whatsoever with them.

Go NGK, is my advice to you all.

 

I used to think platinums were the way to go, but the reason they foul out is because they are completely surrounded by ceramic. Platinum is a great conductor, but burns to quickly in this environment. It will eventually receid into its insulator. Poor spark. Iridium is great high density conductor. Ask a lot of people at the track(land or water) and they run standard NGK's. Good plugs, cheaper plug changes in an environment where they see heavy duty use.

 

Yeah i'm going to go with the NGK Iridiums soon.. i just needed some spark plugs at that point lol
