2.00 LBS

Product Description


This is the ORIGINAL billet Corrado radiator neck which has withstood years of relentless track abuse. We have sold thousands of these with NO issues whatsoever. This part is made from 6061-T651 aluminum and is professionally TIG welded and pressure tested by licensed A&P’s (Airframe and Powerplant aircraft mechanics) who spend most of their time working on commercial jet aircraft. Simply put NO ONE can do it better!! We are so certain it wont break, we offer this part with a LIFETIME GUARANTEE!.

Our billet rad neck comes with ALL THE HARDWARE NEEDED including new aerospace grade O-ring and mounting bolts, all at no extra charge!

Don’t wait until your plastic version snaps and drops chunks down in the rad, and don’t waste money on other untested versions. has closed the book on this part and it will never need to be replaced again. Available in as machined finish.  Like most aluminum parts, if you wanted to polish it up, you could make it look better than chrome ! 

"Wife-beater" t-shirt not included. 

This part replaces OEM P/N 535-121-647 (535121647) found on all Corrado G60 and VR6. Comes with all new fasteners and new aerospace grade O-ring – EVERYTHING needed to replace the factory plastic neck.

  1. direct fitment 4 Star Review

    The coolant fitting fits perfectly and is well built. The only downside is the neck could stand to be 1.5 mm turned to the front of the car. The back screw would be much easier to tighten. Beyond that the part is awesome. Time from order to shipped was slow.

    -- Response --

    Ok thanks for the honest review Andrew. We do normally keep this in stock so shipping is usually very quick but this time we were in between batches and had to make more. Corrado is a very limited market at this point so sometimes the lead time will be longer than day or 2 on some of this stuff. Just call or email before ordering if you want to double check. Thanks again and would love to see pics of the raddo !

    Fair price for a necessary upgrade/maintenance part for the Corrado VR6. As with every Gruvenparts item I've purchsed...perfect fit and finish.
