Suggested upgrades
Guys,
I have just bought a evo vi and wanted to know the suggested upgrades.
Do HKS Iridium plugs preserve engine life and do they prevent knocking ? do you notice a performance increase ?
ECU or boost controller ? I know you can manage fuel and air flow with a ECU as well as the boost, but is it necessary if you are only going to run .9 - 1.0 bar ?
any suggestions will be appreciated.
