    Im upgrading to a Cobra turbo bk exhaust with Decat and non res bk box and Hopefully stage 2 re-map.

    BUT i don't want to change the air intake! will I be able to achieve stage 2 with the standard air intake system??

    Ive heard you can get heat soak if you upgrade to a cone filter!!! has any1 heard of this??? apparently Heat Soak is when warm air is drawn in through the cone filter???

    It is possible...I did it,but frankly it's not the best way to go.

    The stock system does strangle airflow at peak rpm and may throw errors or misfires,but yes,it can be done,at STg2....I wouldn't try it at Stg2+.

    what do ya reckon change the air intake then??

    I dont like the cone filters, There must be something thats bigger, id like to get something that really sucks the air in from inside a unit like the standard air intake, with a good flow of cold air there must be one designed already????

    maybe you could attach a small intercooler mounted behind the grille with hoses that feed back to the air intake that would be perfect for me

    I'm pretty sure heat soak is when the intake channel isn't properly shielded and the air warms up before entering the engine. The idea behind a cold-air intake is that you suck air from the front of the engine bay, or from behind the fog light, so it's not being affected by the warm air in the engine bay. A good thermal insulator around the pipe will limit the soak effect. I think a dedicated intercooler for a cold air feed might be a bit much, also not sure what you plan to use to cool the air... why not just channel the cooling air directly?

    Hi, i have stage 2 APR with downpipe and standard air filter. I have been experiencing missfires around 3k and latter around 6k. i presumed it was due to fueling issues or needing new spark plugs, however S3Alex has now got me thinking that my problem may be due to to the standard air box.
    The missfires relly ruin the power delivery and the overall driving experience so i intend to look further into wether the missfires are caused by the standard airbox Can you shed any more light onto this issue S3alex?

    I ran stage 2 with no intake for a few months (since Revo lists it as an optional mod at this stage) with no issues to speak of. I've even had my stock airbox on recently with stage 2+ for a few days (after a service) and while peak power was definitely not where it was with my EVOMS the car did not feel like it was labouring or running any worse.
