    Got mine from ebay, 4 for about 20 quid I think. Being iridium they last longer tho so its worth the cost in my eyes. And yeh you'l need to gap them with feeler gauges

    stick BKR7E copper plugs in it mate. The copper version of what Karl suggestd.

    Copper dissipates heat better, which helps towards EGT's, and with a ko4 hybrid you're going to need all the help you can get with EGT's!

    As Karl said, the only benefit or platinum or iridium plugs is life span, plat/irid plugs will last 50k plus, where coppers need changing every 8k or so.

    However, the coppers are £2 per plug. I'd much rather spend 10 minutes twice a year changing plugs and know that I've got fresh ones than spend the extra initially and assume they're fine for 4 years!

    I run BKR7E copper in my 350bhp AGU, Tuffty runs them in his at 400bhp, and Welly ran them in Bumble at 450bhp too

    I would think the 7's would be fine on a mapped AGU yes mate, if there were a touch cold you could always try 6's, but I think 6's are standard.
