Plugs

psychonosspaz · Jul 25, 2018

Hey guys, I know there has been some debate on what plugs to use when you are running a tune or JB4....my car has been idling slightly low, around 700 at times and I am curious what the best safest option of plug there is out there? I have heard the iridiums are good and the brisk silvers in other posts....any opinions? I'm at 22k miles on stock plugs with about 10k running JB4

Thanks

What type of driving do you do?

Are you running aggressive setting on the JB4?

They usually recommend colder plugs when going stage 2. I’d recommend Brisk Silvers

I’d wait till you do the downpipe and adjust Jb4 accordingly. Rule of thumb is one step colder plug for every 100hp you increase

I prefer OEM RS7 plugs, but brisk is another popular option as mentioned above

I'm going to put them in at the same time I install your DP

I replaced my stock plugs with stock plugs at ~30k. Since the change, I've done Stage 1, 2, now 2+ (IS38) on Unitronic tunes with no drama. Another datapoint to consider.

You know i have seen everyone jumping on the more expensive plug bandwagons and cannot say enough that the IKH24 's have been great for me. I have ran the Brisks and while they were good, they required more regapping and had a higher price than the Desnos. This is good for me because i can find the IKH24s in stock for cheap, but feel bad everyone thinks they need to run $10-$20 plugs.

how often are you/have you replaced them?

Twist1 · Jul 26, 2018

I've tried all the three popular choices in order. I settled on rs7s. They seem to run a tad smoother and have less misfires than brisks or other colder iridium's. However, they degrade much much faster. I change every 12k maybe 11k just to be safe and regap at oil change interval. Regapping is crucial to optimal engine performance especially at stage two levels.

For those running RS7s and the others, where do you order from for the best deal? Can you give me some links? Thanks

Can anyone say how many miles plugs are good for, and after how many miles they should be changed. I have the stage 1 eurodyne, are stock plugs fine, or should i be running different plugs?

Another RS7 plug user here.

My last set I got with RS3 coil packs from HStuning.

I use DAP b/c Paul is a good guy and his prices are fair. I also like the DIY videos they freely contribute on YouTube.

This is going to vary depending on a dozen factors.

My stock plugs lasted 19k miles (17k tuned) before idle quality and drivability were compromised.

With the bigger turbo and more boost, I'm not even getting 10k.

George at BMS will recommend stock plugs. You just have to gap them tighter to about .024-.026.
