I am having a top fabricator make an exact copy of the original GTA Airbox and Snout. The parts will be made of aluminum and look as close the original parts as we can get it. I have seen other copies but none look identical to the original parts and I have no interest in a carbon fiber one. The buck is being made now. Obviously the cost will come down if more than one of these is fabricated. Anyone interested please send me a PM.

These will not be cheap but if you want something that looks original this is the way to go. In a concour if the judge can't tell the part from the original you don't lose points. We are also trying to find a way to fit a filter in the airbox but can't promise that just yet.

Hey Bob, how did you figure out it to be correct to use an aluminum GTA box versus the Fibre glass type for your GTA. I have the fibre glass type with 752507 but don't know if it was original to the car.


Ciao

Ken the first GTAs had the all Aluminum airbox per Roman and other Alfa Gurus. Scott Gray has provided me with three examples. The first one is a perfect all aluminum one and the second is the same design with the aluminum covered in fiberglass. The theory is that later in the life of the cars the airbox was covered in fiberglass to prevent cracking. I have decided to go with the original 1965/1966 look (aluminum) to be true to the original car as raced in 1966.

Not sure on this: but aluminum was original on the early Autodelta prepped cars though not homologated for 65 - it was FIA homologated December 1966, valid from January 1967 onwards - though definitely used in some cases earlier than that. I have a factory fiberglass box that originally came with the car with what appears to be a metal tag with some letters and the number 68 punched into it - possibly being intended as a homologation tag. The car is a late 1600 with the later GTAjunior style suspension and wheel arches that was homologated for 1/1968.

I have always assumed that the fiberglass box originally went with the later cars - 1600's and particularly juniors - and that 68 may have been the intended homologation date, though I have never seen a homologation document other than one for the original aluminum box - they may have considered the change in material as not necessary to homologate separately after all.

BTW, the box is definitely fiberglass only except for the metal tag. ^^sounds like an early hybrid box w/ aluminum covered by glass.

My car was prepared by Autodelta in January 1966 and shipped to the USA in February 1966 hence it should have the all aluminum airbox. Based on what you are saying the all fiberglass version is correct for some cars. I am only making the part that would have been on the 1600 GTAs in 1965/66 and must rely on people like Roman Tucker, Scott Gray, Max Banks and Anthony Rimicci regarding originality issues. Anthony Rimicci provided me a damaged all aluminum air box that came with his GTA. We had four airboxes to examine and the construction was the same on all except the one covered in fiberglass and it was only different as to the fiberglass covering.

Original snout, tooling and first article

Here are some photos of the tooling and first article. I have included a comparison with the original snout. There are two original snout samples we received from Scott Gray and one is butt welded and the other is flange welded. We have duplicated the butt weld version.

Let me know what you think. The nut plate has yet to be installed.

OriginalGTA Cold Airbox

Here are some photos of the original GTA cold airbox we are using to make the reproduction part. The metal plate that attaches to the carbs is not shown but it will be duplicated as well and is an easy part to make.

Fiberglass over Aluminum example

Here is another Original GTA airbox that has been glassed over at some point.
Parts and photos from Scott Gray. We are duplicating the straps as well.
Note the vent in the end for pressure equalization.

Still waiting on price quotes

Thanks to everyone that has responded. I am still waiting for a detailed quote on the price. The fabricator just reorganized his shop and has had some delays. He promised to get me prices this week. For all of you that have been involved in restoration you know that craftsmen can't be rushed.

I am also searching for the a proper rubber or silicon sleeve to connect the snout to the airbox.

GTA Airbox and Snout update

To all interested parties here is the latest information. I have taken delivery of the first snout and installed it in my GTA. The fabricator has made a prototype of the airbox but has no pricing and is redoing his tooling. To complete the airbox the fabricator needs to make the plate that bolts to the carbs and the straps.

Scott Gray Loaned his airbox and snout to the fabricator to make the parts and will be the one selling the parts. I will not be selling Airboxes or snouts!

The parts are not going to be low cost due to the high labor content. There may be some fitment issues with other (non GTA) Alfas and Scott does not want to sell individual parts like straps or sell the snout for other models.

Thanks to everyone that has responded with interest and encouragement. I did not set out to be in the airbox business and was just hoping to reduce the tooling costs. I know everyone wants to know the cost. I don't what the final costs will be but to ball park a rough estimate the total cost for both parts will be north of $5500. I hesitate to throw out this price but I doubt it will be be less and if it exceeds your budget then you can make other decisions. To those that did not have a heart attack at reading this price. The parts are world class and worth the wait. When I have the final airbox I will post the photos. I will ask Scott to post his contact information.
