focus st170

Hi I've just bought a 53 plate ford focus st170 but am finding it hard to get bits for it. I wanted splitfire plugs and wires but can't find any to fit. Any ideas as to what else I can do instead?

Try the NGK Quad electrode or even the NGK 'IX' plug - the effect is similar. If you sign up to the forum - you will find some other st170 owners in the Ford section and it'll be worth asking them also.

Doubt if you'll get an 'IX' plug. I would recommend champion v-groves they seem to work well for me.

how will changing the plugs affect performance? will it make the enging any more free revving or is that just a characteristic of the duratec? i got an st 170 myself its a great car, handles superb and is quick where its useful, ie 40-90 odd.
also do you know of a good brake upgrade?
cheers

A good plug gives a strong spark and helps get the flame front set up correctly in the cylinder - the thinner the electrode the better. But to be honest their is not a great deal of difference between a high performance plug and a fresh OEM plug.

Brake conversions = are you thinking just pads and disks or are you looking to get a much larger brake disk and upgrade to a 4/6 pot? EBC pads are pretty good - greenstuff generally for the road.

PS: NICE TO HAVE YOU ALONG TO THE SITE AS WELL!

hi, thanks for the welcome.

i was thinking about just upgrading the pads, i heard that greenstuff pads give off less brake dust as well as improving braking which would be a nice side effect. cleaning dust off my alloys aint too fun.... is this true?

if i did decide to go for bigger discs and pots, which would be any good? and how much could i expect to pay?

cheers

Price varies a lot but a bigger disk will help braking a lot. I loved my Greenstuff pads - great stopping power and less dust (there is still some but a weekly job of cleaning turns into a monthly job!)
