993 GT3 airbox question

[BrianM]

I have a 97 993 C4, will I notice any difference in fitting a GT3 airbox and K&N filter ? Thanks.

Not sure about GT3 airbox. Have seen 993s with the 'Cup airbox' I think it's called, which is just an airbox with cut outs in it for more airflow and a shiny intake. Difference in power is negligible, you get a bit more induction noise, but as Paul Daniels would say, not a lot.

As far as mods go, changing the exhaust releases the 911 character from a 993. Chip and filter are fine as sensible and cheapish mods at the same time, but airbox makes no massive difference in isolation.

Will some sort of Gruppen M carbon air box have any imapct on the vehicles, Herr Domst?

I do hope so because there's something undeniably catchy about the phrase "Gruppe M;" sounds like a formation of battle hardened Stukas.

My dear derestrictor.

If it is a Gruppe M airbox you are seeking, unless you are a recent lottery winner, please ensure your posterior is firmly seated before enquiring of the price....

Brian, I have the OE Porsche "Motorsound" airbox retro-fitted to my 993 C2. I also have the K&N filter. The difference over standard the combination is huge (in induction noise terms) I might be daft, but the car seems to rev much more freely in the upper range, and it sounds great.

Unfortunatly, that is it all it is! Alas, I think no performance gains with these mods.

In support, a freind of mine went slightly further and fitted a cup airbox and K&N filter to his `96 993 C4 and he raves about it. Yet again though, I think its all noise and no ooomph!
