I have one of my custom box if you’re interested.
Same power and performance as the Renntech but no carbon fiber.
Mine gives you the oem look.

email me if you or anyone is interested.
Thanks. Speed43Mods@gmail.com

Why?
Been selling for 7 years just fine. Maybe 2 people have asked for carbon during that time.
What’s important is the inside of the air boxes, removing the bottleneck that restricts not only airflow but breathing for the engine. And adding more air space inside the box, Contact renntech if you really have to have carbon fiber. Be ready to pay big money to buy one, and you have to provide them with your air box, shipping price to get it there, and when they’re done pay shipping for them to send it back.

My buyers are looking to keep their car OEM as much as possible but with better performance I offer them that option.

Ive never had a cone filter on any of my cars.
So I can’t say, but if you buy one of my air boxes you can have 7 days to return it for a refund.
Just please be honest that you really want performance with the oem look.
That way I know you won’t return it because I know you will love the performance and look!

My main concern is the effect of tuning which the current car is set up for.
It has Kleeman headers/exhaust/Jerry's TCU and ECU tune
Would changing the air flow not affect the tuning and causing lean or rich situation or you don't think air flow would change much?

Should make it even better. I had Jerry’s tune with my air box and it was awesome.

Wanted to post that I’m all done with these special modded boxes.
From here on I will only make them per request.
Im going back to the original modded air boxes and thinking of selling them for $525.00.WITHOUT your core, and $405.00 if you send me your core. You must pay full price till I receive your core. Once received I will send you $120.00.

Thanks for reading.
