With some time on my hands (recovering from surgery) I came up with a way to stop the bottleneck our oem air boxes. The picture with the red circle shows where the bottleneck is. (Side note the pictures of the air box shows in primer and the other paint still drying…)

In the past I just raised the air box by splitting it in half. I’m still doing that but now I’m cutting off what I’m calling the THROAT. After cutting that off I raise that section so there will be a huge area for the engine to breathe.



Not an easy job for sure but it makes a great difference at half or wide open throttle. I’m also modding the middle top portion of the air box. This has that step like between the front and back of the box. Inside the box it’s like a step so I cut it off so it will connect with the back and front part. This makes the air inside travel smoother and faster as now there’s no interference in air flow.



I’m also modifying the front sides, making it more round for a little more air space/volume inside, and it looks nice out side the box..



Making the air boxes I’m still using oem plastic to weld and for structure. But now I’m also using fiberglass, I don’t like working with fiberglass but it makes the air boxes super strong all around, so it’s worth it.



I’m only going to make few of these boxes and put them on the side for those that appreciate this kind of work and effort. It will be expensive so that’s why I’m only making a few of them.



Price will be $600.00 shipped within the USA. $490.00 if you send back your core. Sending back your core that you will NEVER need is the best way to go to buy this air box, it’s up to you.



I’m still offering the original air box for $545.00 shipped within the USA. If that price is better for you.



I know many here already know about my air boxes and some already own my air box. But I always get emails people asking if I’m still making them. So this post will help me out..



Thanks for looking.

 

Hey Geo.,
be sure, you are always one of creative genius ever seen, noooo doubt..

(-;-ZAYED-;-)

 

Thank you Zayed, just trying to make our cars better and put some food on the table.

 

Here’s the finish product. My goal was to make it a bit different and to make the throat of the box bigger to remove the bottleneck the oem air boxes have. Try sticking your hand in your unmodified air boxes, even your child’s hand will not fit in there. So good amount of air will flow into the engine.

If your car does not perform better send it back within 7 days and I will give you a full refund.
I know you will keep it if you’re looking for performance..

 

George, you've nailed it perfectly. Great job as usual

 

Thank you Daniel. Now just need to keep selling these for at least one more year.

 

Interesting modification. I like the smooth almost seamless appearance of the finished product. Besides increased airflow, are there any other benefits? Like weight, or rigidity?

 

Thank you. Airflow and more air space inside is what I like about this box. Also it is more stronger because I use oem plastic to weld and not abs like I use to years ago. And now that I’m using fiberglass it’s much stronger than before. You won’t notice much difference in weight compared to the oem box. You will notice better throttle response at any RPM. And more torque at the low end and more HP at the high end.

If anyone doubts this, check it out for yourself. Buy it, use it for 5-7 days and return if you didn’t notice any difference.
I will give you a full refund, I will keep your funds in PayPal and refund you that money the minute I get my air box back.

Btw I have a customer that just paid half for an air box and he will be sending the rest at the end of the month.
I have done this a few times and will continue to do it. Send half I will start on one for you, or hold it if I have one already done. And you have two months to send the rest, once I receive the rest I will ship the box to you.
I’m a one person doing this work, I’m here to help you get better performance. I help you with that and you help me make some extra cash.

Email if i can help or if you have any questions. Speed43Mods@gmail.com

 

I have another air box ready to ship for anyone interested.
‘If the price is high for you email and I will give you a great deal.
And no need to send any core, unless you want to.
Thanks.

 

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.

 

Hey everyone, I have two more air boxes ready to ship for those running into this thread. Just email me at speed43mods@gmail.com

Thanks.

 

I just noticed you are from Bolingbrook. I am very familiar with Aurora Illinois, made famous by Wayne’s World 1 & 2, and Fermilab!

 

Yes I’m in Bolingbrook but have never seen those movies.
