Nice one Johan, they're great upgrades! I noticed the polo was more rev happy with the ECS pulley and the engine seemed to rev harder with the colder plugs also. Did mine separately so you're getting a whole lot of love doing them at the same time :eek:
And I also recommend getting a Verdict Motorsport O2J aluminium shift bracket bushings to complement the 42 DD shift cable bushings. Gear changes feel more like an exotic car now!
