Spark Plugs

[Cupra#Ben]

Hi,

Im after some help on uprating my spark plugs.
Ive had a look at the NGK and the Denso's but not sure as ive read a lot of people have had problems with the Denso's.
Wanting to go cooler.

Any help would be great on the comparisons between these and standards.

Denso's are good sum vaux owners though had probs with tips breaking off into the engine.

NGK's all the way, wouldn't consider anything else, would just fit the plug they recommend as far as uprating goes you wont get more power from a fancy plug!!!!!!! Although you might lose power with crap plugs!
