I'm going to be looking to start some basic tuning on this engine next month, maybe changing the air filter, plugs, exhaust etc.
I've done work like this to nearly every car I've owned but my aims have been different in the past, I'm after a more refined setup this time so I thought I'd ask a few opinions before I get cracking.
1. What plugs would you suggest, are "performance plugs" worth it?
2. Would an engine remap be worthwhile, they're quite expensive and I don't really know if it would make a difference to this 2 litre 4-pot?
3. Any suggestions on air filters? I did consider going for an induction kit but I want to keep the car looking fairly stock, a slight induction roar is nice but I don't want another noisy car!
4. Considering going for the twin-pipe scorpion backbox - again, I don't want a noisy car or massive tailpipes - just a "bassier" sound and a tidier back-end!
