C43 Custom Air Box For Sale.
 

I have this air box I'm selling. It will make your C43 run much better than the stock C43 air box. The air box has been tested and made 10HP/10TQ. And helps the engine breathe much much better.

Price is $545.00 shipped within the USA. For other countries you need to send an add6and I can check shipping price.

Keep in mind you can't get one anywhere. Im the only one making these boxes that keep your car looking oem.

I can vouch for the quality built and it really does allow the engine to breath fully. Jump on this people, you won't regret it!

Thank you Daniel. I don't get why these guys don't want better performance. It's not about the extra 10HP, it's the extra 10 pounds of torque that I like! Great for city driving.

Absolutely. Agree 100% 😎

+1,

also; i really hate the narrow poor inlet air path, on "C43/Clk55/E55"..!,,

as a result of less air quantity = less air density>>>BAD PERFORMANCE, especially when air temp. rise-up..!?:nix:?!,,

IMO; Geo.'s airbox mod. is the BEST solution to wake these monsters..:zoom:

-;ZAYED;-

YES x1000!
This was one of my favorite mods for the C43. Looks factory and blends perfectly in the engine bay; well crafted :y

Thanks guys for the kind words, really appreciate it!

Does this price include shipping?

Yes, I include $45.00 for shipping. That USUALLY covers FedEx 3-4 days delivery.

I started working on another air box. It will be ready by Thursday/Friday. Anyone that's interested contact me and I will save it for you. Thanks.

I can vouch as well!! Speedy Turn around, great craftsmanship...

^^+10000000000^^, no doubt..:y

Jeez NOBODY???

I guess the majority of owners must spend their cash on flashy stuff which can be seen and looked at when cruising around, not the more obscure parts that lurk under the hood and really improves performance ;)


One wonders what's the average age of owners on this forum page :confused:

Thanks guys! And Daniel I agree with you. The work that goes on this box and the performance gains it gives you would think people would jump on it.

Hi Geo, are you still making variants of the airbox? I recall that you designed one that had an even wider opening. I sent you a private email yesterday. Thx

I make them high enough to make power but not touch the hood when flooring the car. Each one looks different as they are hand made so they will always look a bit different but same performance. I did get your message and I clicked the link from the email and responded. It was a weird link, never seen that before. Guess you didn't get it. Can you email me directly and I will respond again. Thanks.

Just an update I sold this air box. For those that emailed wanting one you will need to send me your air box or send payment so I can order one from eBay. The prices for these boxes have gone up so price may be the same or a little higher depending on what I pay on eBay.

If one of you guys have one for sale let me know. Thanks

Hey I have an intake (just back part) for sale, no front part that sits on the oil cap, just like the one in this video, inbox me if interested

Thanks, I have pm you.

Sorry I don't do that. Check the reply I posted to your question on the c55 forum. Thanks.

P.s. I will have another C43 air box and modded elbow by Friday. Anyone interested just PM me.

Thanks.

So, I just installed one of Geo's fine modified air boxes on my perfectly stock C43. The first good news is it still looks perfectly stock! The greatly increased height of the rear of the air box is so subtle a change when installed that it looks like it should be just the way it is.
The second good news is it was easy peasy to make the changeover, even including the modified elbow, which fits below the MAF device. The car ran a bit rough at idle when I first restarted following the install, but in about 5 minutes of driving it settled down, and now it's perfectly well behaved, as always.
Can't specify the 10hp/10tq is there, but the car does seem to be even more responsive to the right pedal than before. (Hardly seems possible...:)) I am considering doing the Eurocharged CPU tune, available here in Houston, so if I do that I will try to have before and after dyne runs done at that time. I still have my stock air box and elbow, so I can do the whole series.
Geo is very easy to work with, and does exactly what he says he will do, every time..
Highly recommended.

Thanks for the post and review.
This is the first ive heard of a rough idle at the beginning while using my air box. I think maybe the connection at the throttle body might have been a little loose. Either way glad it fixed itself after 5 minutes, really weird but glad it worked out.

Also, doing a Dyno side by side with stock and modded air box is interesting. Because the ECU needs to adapt for the increase of air coming in. That don't happen in minutes. I've had customers tell me after a day or two the car started to feel more responsive. And that makes sense because the computer is now feeding a bit more gas to welcome the increased air coming into the engine.

Im not an expert but that's how I've noticed the increase in power in my first tests with my air box. The more I drove the better the car pulled. But who knows maybe a Dyno one air box after the other may work....

For sure get the ECU tune, let them know you have more air coming in... After the tune you will feel the car pull hard when shifting to second gear. If you floor it and get the kick down it will really go!

I will have this air box for sale this Tuesday if anyone wants it. This air box has different better material to put it together. I now use OEM plastic combined with abs high heat resistant plastic.

Price is $545.00 shipped. The air box will be painted flat black as usual. Contact me or PM if interested.
Thanks. speed43mods(@)gmail.com
