Cheers guys, its hard to see if its made any difference as i am really not trusting this car in the twisties so not gave it a test yet. Was awesome on my N/a though. Picked up the rest of my service items yesterday (NightWorx Sump bung, Eneos Nippon Oil, Geniune Toyota Filter, NGK Iridium 7 plugs) so started with doing the oil and filter. What a nightmare they are to do on a Standard FTE Engine. Managed to get it sorted with a lot of shouting haha. Hopefully fitting the Iridium 7 plugs tomorrow.
