Spark plug question

[A3tell]

Does anyone know if the ngk BKR7EIX iridium plug fit an AGU a3??
Just want to double check b4 I buy, as I can't find a compatibility chart!
cheers.

7 is too cold for a stock engine, you'll want 6's unless you've upgraded the turbo substantially. Probably somewhere above 250 before you'd want the 7's

I use BKR6E's, which are copper.

No need for fancy plugs imo, just nice standard copper ones changed often.

I have had mine mapped, just recently started small hasitation on accel and I know the smaller tipped iridiums give better spark!!!
i think I put the platinum ones in last time!!

Tip size doesnt make any difference to spark strength, and if anything copper conducts electricity better!

If your using 7's in an engine thats only remapped you may find them fouling up which will give you issues.

i'd stick with either the BKR6E, or the standard PFR6Q plug.
