nice review there Jags,
things you can definetly go far
1. K&N stock replacement filter, improves the drive ability of car with AC( u will find the difference only after 1000kms with K&N)
2. get engine oil changed to Synthetic one.. it makes the engine smoother, revs without a cry..improves the responsiveness of the car.. definetly worth the money
3. a NGK iridium spark plug, what we have in 1.2 is a champion RC8BYC, check the equivalent iridium here
Spark plugs UK - Champion, Denso, NGK spark plugs and Magnecor leads, u get a equivalent BKR6EIX NGK iridium plug, available at N1 engineering in bombay
enjoy your ride.....
FIAT, always....
