Plugs question on turbo S197

[Vashthe3rd]

Simple question, it's time to change the plugs, car sounds like ass
Do I go one step colder?
Considering E3's, opinions? I've heard different tales from either side, some say go with stock plugs, some say go with a new brand, some stay stock temp range, some go one step colder.
Facts, and opinions please! I know very little when it comes to the ignition system compared to the rest of the engine.

HT0's FTW.

You could go brisk but from what I've heard, they don't last as long.

i wouldnt have a power adder on my car without a colder plug period.

 

[Bobby]

go with the ht0 gaped at 30 that is the best plug i have found so far.

 

[stkjock]

go colder, HT0s or Brisk 3vr14s, gap .030-.032 IMHO @ 10 psi

 

[Vashthe3rd]

colder HT0's it is then
I'll hopefully be swapping them this afternoon, we'll see how it goes, I'll see if my buddy has a gaping tool
EDIT: As for not going one step colder before: Originally my tuner said stock plugs were fine, I backed it up myself looking around on the net and saw alot of people running stock plugs with no problems on the same setup, car worked fine but it's obvious it's time to be changed.

ht0 or the brisk's os what I'd go with

I personally run the brisk plugs

Quick question now that I've tried looking around town
Anyone know of any auto parts chains that carry plugs in different heat ranges, so far the main ones have been either out of plugs completely, or don't carry anything beyond stock heat ranges.

We do shipping and even shipped it usually less than picked up, but any local performance shop should have em.

I'll look around, but if I end up ordering I'll hit you up, trying to get this done this week so we'll see what happens.

there you can find brisk spark plugs retailers, I'm not sure exactly where you are but the list should have some one around you.

 

[Vashthe3rd]

Ok so interesting facts:
1) pulled plugs turns out I've been running ht0s
2) swapped to ht1s which I was told were 1 heat range colder
car now misfires in any boost but runs and sounds fine out of boost were thinking some or all aren't torqued down
ideas?

 

[dysan]

HT1's are one range hotter not colder.

Edit: hotter than the HT0, they are the stock heat range as stkjock posted below.

 

[Vashthe3rd]

I am now very pissed
I'll be going to the shop who sold me these and raising hell tomorrow
