Hello, I have a Karbonius 2x2 Matte Finish airbox and snorkel for sale. I bought it new from Karbonius and used it for ~7k miles. I sold the sedan swap and will be moving on to new projects :-) No longer need it, and hope you enjoy it as much as I have.
PSA Soapbox - I think the most valuable asset here is the combination of the ECU tune and the hardware setup. I've had two CSL airbox setups over the last decade and lots of tunes: Karbonius box, Evolve box, Stock CSL MAP tune, Alpha N evolve tune, various unnamed "tunes" from tuners I won't mention. They all knocked, bucked, and below 3k rpm in daily use were "meh" to say the least. The tune Bry5on put together makes this a real, driveable, and generally lovely thing to own. Not many people drive multiple setups, but the difference is night and day. It's the difference between feeling like a tuner car and feeling as if an OE engineering team spent time on it. No messing with the knock sensors, none of the tuner weirdness that sacrifices longevity for power. Yes, I'll say it out loud... I've seen the parameters.
Included:
The only blemish on the box is where the bolts attach, pictured below. Of course, you don't see this when it's installed, but you should know.
$3.2K plus shipping, insurance, and fees. Prefer local pickup in the Bay - will discount for that.
