I cant find the right plugs.... the ones that was reccomended by the dealer were 35$ each + tax... lol i rather never boost again than spend 150 on plugs.

i know for the 8's ya guys found good plugs for 5$ each, or something super cheap idk...


whats the model for the 9 and where can i get them?

link anyone?


Thanks!!!

 

Don't be cheap, get the good ones!


What type of plug did they want you to buy?

 

 

well i heard of the denso spark plugs... they suppose to be as good...?

i heard i can get those for less than 1/2 the price... i just dont know the model number

 

I believe NGK's are better, at least they were for my 04 STI.

I want to know at what point is it good to consider going with one step colder plugs, and what the NGK model number is for those.

 

Denso ikh24

 

i think im going to go a step colder... i just got the meth installed... and im sure from all the logs it beat the hell out of the plugs... its driving fine... but i rather change them out when i have time, instead of having a problem on the side of the road

cheers!

 

One step colder: NGK R7437-8 Spark Plugs (0.026 Gap)

 

i was told that the 9s only like the stock plugs... I ordered some already...

 

Im not sure if there is a differance between part numbers on 8 and 9 plugs but i run NGK's part # 2023 there 1.77 a piece. Probably the best plug u can run, you have to change them more often than the $20-35 ones. But that never bothered me for under 2 dollars a plug. cause everytime i change them, i know i got full power.

 

IX plugs and VIII plugs are different animals. THEY DO NOT INTERCHANGE EITHER WAY. IX's are very limited as to the plugs available. Denso 22-24 and Racing Plugs from NGK. R7437-8 and R7437-? Can't remember which heat range. Stock is ILFR7H I think.

 

hmm....

so 50$ on the denso's or 150 on the stock plugs

idk what to do

 

Spark plugs.com has the NGK ILFR7H for 11.71$ alot cheaper than the dealers

 

The plugs are longer on 9s. Supposed to use stock. Non-stock plugs work but who knows. At the moment I am using Brisk racing plugs.

 

i have been using the NGK ilfr7h's, im on my second set now, keep throwing a p0301 code, have been for awhile since the changes. I am going to try the stock plugs again i think.
