Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I drove a 2000 C2 with an air box and it opened up the sound a bit on the stock exhaust. Is it worth the $225 or so for the do it yourself upgrade for my 1999 C2? I was told that on a 1997 Turbo, the owner just removed the stock airbox, drilled out the undersite with 1 inch holes, replaced it and had the same effect.

POST 2Original post

If you drill holes in the air box, you are just going to introduce hot air from the engine compartment. I would think that is counter-productive for performance. You really want cold air from the spoiler/intake.

POST 3Original post

The only airbox worthwhile is the fabspeed one.

POST 4Original post

sorry to say, the fabspeed airbox mod is the cheapest one but not the best one. the fabspeed is a waste of time and money.

POST 5Original post

try the orange cap mod. It'll give you the same sound and it is almost free.

POST 6Original post

Funny, i said the same thing about the evo. I don't think any of them really do all that much, I just liked the fs better.

POST 7Original post

None of them really do anything except make a better sound...

POST 9Original post

http://www.smiley.net/orangecap.htm Here it is. Anyone have an extra cap for offshore?

POST 10Original post

I'd love to try the cap mod... anybody have a spare one in Toronto?

POST 11Original post

POST 12Original post

you hear more intake noise. kinda like an aftermarket airbox (they say). I also found the low end response a little quicker... less air to move from lower to higher speed. I'm sure I paid for that somewhere else in the powerband.

POST 13Original post

You found the low end reponse a little quicker from the orange cap mod? That's not possible...

POST 15Original post

we could do a group buy for the orange cap (200 for $29.00)

POST 16Original post

Gotta also flash the ECU to make a difference...

POST 18Original post

The stock box already flows more air than the engine needs, the only thing better would be a dual snorkle cold intake like the new 997 X51.

POST 19Original post

I have an extra orange cap laying around..I would say I gained around 4 hp doing this mod ..pm me if your interested
