Well my car passed first time on saturday, I had the test done early, so that's me in the clear for 25 months.
The only prep work I did was to change one of the numberplate bulbs, which had blown, only copped this the night before the test. I also swapped back in the original air filter and box -just a precaution.The ITG needed a clean anyway.
I'd forgotten how quiet and subtle the mivec system is, with the standard air intake.
