Please dont me bad, i search and couldnt find any stock numbers for the spark plugs for 03 lancer. Please help. I went to NGK site and it said the stock number is 4055 but then i went to get them they weren't right. it was the the evo. i work at baxters auto parts warehouse and i just need to see if we have any instock. i went to autozone(they dont carry NGK), shucks didnt have them and the people at baxtesr said they are out. i want to check it out myself. since im there everyday for work. i dont want the item numer, i want the stock number. thanks in advance

 

I'm sure someone will chime in on that... BTW, do you work on the Pacific Hwy location? If so, I might have actually saw you in early Sept when I asked for a ODB II reader for mom's minivan. Anyways, good luck and good choice !

 

Stock number 5464, plug number BKR5EIX-11, gap to 0.44", should be about $7 each.

Waste of money, in my opinion. But that should be all you need.

 

it might help getting better sparks...
no use for minor tuned car...

 

I've got NGKs installed and here's what I noted in my registry:

Idle is much smoother and RPMs on a cold start only reach 2k instead of the usual 2.5.

On the highway revs feel much smoother as do shifts, without much of a boggy feeling when getting on the gas. At 80mph, rpms have dropped a tad from 3.5k to a shade below it (~3.3k).

 

I had them and here is what I noticed... Less money in my wallet. Pissed me off and I will only use regulars from now on.

 

just use regular plugs. Its less money and they do the same.

 

I got the ix twice now and they burned out my coil pack both times ... i dunnno why... i changed to laser iridium by ngk maybe it won't burn them out. but sux cuz they burn out in a little more than a year so my warranty doesn't even apply .
