i am wondering how much would the stock spark plugs be?

 

i dunno but I am curious too...i am having all kinds of engine trouble and am considering replacing mine

 

me too..what problems do you have? my problem is that the engine lags around 4-5 thousand rpm...like it would rise then stop at 4500rpm...i dont know the problem..i checked the intake, the diverter if its plug in tightly and i check my downpipe..i am curious if the spark plugs would fix the problem

 

OEM plugs run about $20-$25 each. For 1/10 that price you can pick up some NGK BPR7ES plugs and probably have better luck. I've been using them for years and they work great.

 

$20-25 each..wow i thought they'd only go for at least 35 bucks for all 4???

 

They retail for $25 each!

 

I am having a similar problem....my car runs fine until it gets hot.....then the as soon as the heaviest boost starts to come on the engine feels like its cutting fuel....in some cases the engine won't even rev all the way to redline. Its screwed up...they have replaces the wastegate syllanoid and that did nothing...they also told me the blow of valve had gone bad...which it hadn't. I think it was something to do with the ignition

 

i have another thread that I started concerning the problem I am having..there are all kinds of possibilities.....how many miles do you have on your car? Have you ever gotten an popping/backfire noises when you stay on the gas when its lagging....or any weird engine noises?

 

i can vouche for bpr7es's (ngk) been using them forever & they are the only plug i would use. plus just bored the other day & was reading my warranty manual.....guess what, it says that the oem plugs are ngk's. go figure

 

It could be the brand of fuel you use. I have noticed that I get this problem more often with shell gas than other brands. It rarely happens with other brands.

 

Nah its not gas...i use BP, Shell, Gas America, Speedway..you name it...something is seriously wrong with the car...its fairly violent sometimes when it cuts power.

 

i have backfire noises through shifts...

What are the cheapest plugs that would work evo...and where could i get them??

 

Buschur sells some better plugs that are not outrageous!

 

Any auto parts store that carries NGKs can get you these or you can order them on NGK's website.

 

SummitRacing has them too!
