just bought a set of these. If heard off a knowledgable mate that chances are I'll need a more powerfull coil pack something in the 40,000 region compared to the 32,000 standard.

Anyone had problems on standard coil pack?

No the standard coilpack is fine.

And those spark plugs are crap too.
NGKs are much better

Bosch super 4s this is just an economy spark plug when one of the ground electrodes wears the spark moves on to the next ground electrode
you could try bosch spark plugs wr dc/wr dc+
or iridium spark plugs denso/ngk denso's give more spark energy for a shorter life cycle and ngk gives less spark energy for a longer life cycle

this is a beginners mistake the worst that can happen is burning a hole though the piston crown seen loads of holed pistons but not on any of my engines

thanks for your advice 20valver but i just wanted to make sure they were ok, i think racing spark plugs is a bit OTT for my engine.

just received these, they are a FR 91 X code, every seller on ebay lists these as the right ones for the x16xe engine.

But in the haynes manual it says the FR 91 X is only for the certain other engines not the x16xe

the x16xe is listed as needing FLR 8 LD+U but no one has these for sale.

Had them in for around three or four months now.

They have been absolutely fine.
