Is it standard or mapped?

if standard Bosch Super 4's or NGK Platinum
if mapped I use Denso IK22's I think they are called but they are £40 a set  :sick:

using NGK PFR7Q's which are a stage cooler than the 6Q's previously had in.

the PRF6Qs I believe are standard fit replacements for AUM/AUQ and 225 1.8t's.

Did occasionally get misfires coming off throttle but heard no pops or bangs  :grin: since changing to the 7Q's, seems to running be a lot smoother as well.

What power are you running?

My ARZ runs fine on the 6Q's but might try the colder 7Q's next time there due a change
