Hi Guy's

plan on giving it a good service before i do a few small mods.

Planned mods are:

Z4 ECU
Uprated fuel pump (play it safe)
Decat & full exhaust system

Nothing major.

What should i be using for servicing this is the first time i have done it myself on a WRX.

What plugs?
Oil Recommendations?

Thanks

As for oil best use the search engine as it has been covered a few times I use to use 10W60 Castrol RS in my 93wrx for 6½ years and my Type R for the last 1½ and it was fine BUT many people on here will say that's a not good and you should use 10W40 (I'm not recommending 10W60 just telling you what I've used)

 

Same as myblackwrx says.

Except i've always used a good quality 10w40

 

If you're de-catting, dont bother with the Z4.

See if you can get hold of an ECU that has one of the chips in place that have been sold over the years by the likes of "Polar performance" and recently the Scoobynet user "Major Sarcasm"

These are perfectly safe and have a map for the de-cat and 97 Ron + fuel.
