Upgrades in the engine bay
Folks,
Replaced my stock airbox with a BMC conical filter and a special made adapter to convert the airflow efficiently from the round filter to the rectangular air flow meter.
Not sure if I like the hissing noise at some specific throttle settings but it sure made a difference. Small but very noticeable at above 4k RPMs.
Not done a new mapping yet, that will come with a soon to be installed new exhaust system with headers and 2 catalytic converters.
Did also add a fire suppression system. It is a plastic tube filled with a liquid gas. In case of a fire it will burst open and discharge and hopefully do its job.

Very cool!
I like the clean look of the aftermarket air filter, but wonder how much of a pain it will be to clean. Curious to hear what the performance gains are, if any.

The fire suppression system is made in Slovenia, not sure if there is a source in the States. http://www.atservis.sk/
On the air filter I can clearly say that the positive effect is much larger than I thought it would be. Now I don't have dyno'ed it before and after, but the gains are very noticeable. Mind you however that it needs a well designed adapter converting the air flow from the round filter into the rectangular air flow sensor.
The guy who designed the adapter recommends turning the whole sensor by 180°, so similar to the 964 set-up, it should improve the flow even a little more.
