The Ultimate Crackpipe - All VR6

4.10 LBS

Product Description

12V, 24V, and Touareg/Cayenne VR6 Billet MODULAR Coolant Pipes aka Crack Pipes 

If you dont want to ever do this job again, buy the LIFETIME WARRANTED billet Crack Pipe ! was the 1st vendor to build this part and it’s what started us off in 1999 ! If you have a billet crack pipe installed on your VR6, more than likely its one of ours. We machine our pipe to EXACTLY match the OEM part shape so there is NEVER a fitment issue. Be careful when considering lesser pipes that do not match the exact shape of the OEM pipe. The fitment of this part is tricky and the shape MUST BE IDENTICAL to the OEM part to ensure correct alignment between the water pump and thermo housing. 

Ours is also NOT MADE IN CHINA (like the Walmart guys).  We are actual VW enthusiasts located in Atlanta, GA who have years and years of knowledge about these cars.  You wont get our level of post sale service at the Walmart of VW Aftermarket, located a little farther north of here.  Do your research on the forums before deciding who you want answering the phone if you have an issue down the road.

Our pipe is machined from super light and super strong 6061-T651 aluminum with TIG welded and full threaded bungs on both the oil cooler feed nipple(s) and the drain plug (no tapped thin wall regions!). Our Modular Pipe allows you to remove the oil cooler feed nipple(s) and plug with standard ¼ NPT plugs if you want to ditch the problematic OEM factory oil cooler and install a more serious air/oil cooler. Likewise, you can also install a temp sender in the plug location, or opt for our plated drain valve to make coolant flushes quick and easy. 

We have owned, operated, and tracked VR6’s for a long time and have considered many features when designing this part. You do not want to have to do this job more than once, and you surely do not want the flimsy plastic version to leave you stranded (or worse : turn your high strung VR6 into an overheated paperweight). Do this job once the right way and you’ll never need to worry about a pipe failure again.

  1. Crackpipe was of solid construction, but i wouldn't call it Ultimate 4 Star Review

    Posted by on 3rd Oct 2022

    Ultimate polished Crackpipe that comes in as half polished/half still spun/machined aluminum with fingerprints all over it isn't really Ultimate that said polished/ unpolished/black or what ever color you do it in, unless you have a shaved engine bay it wont matter as you can't see it anyways, finger prints and all....

    ok all Critique aside, the crackpipe is a major job for installation if you do this job make it a lot easier on yourself and use a finger tip dipped i palmolive dish soap and run it around all mating surfaces to help ease the O-rings into all water bores, you will need good steady push to seat them and you will feel a significant thud when they are seated.


    OK thanks for honest review Jeff. Sorry the pipe had some fingerprints on it. You can run a bit of scotchbrite over the OD of pipe to make it gleam but I guess they left it a little dirty. Hopefully you liked the fit and the machining/welds though. Let me know if you need anything else.

  3. Nothing but quality! 5 Star Review

    Knowing how difficult the factory part would be to change with the engine in my 01 GTI, I went ahead and picked up the Gruven ultimate crackpipe. I doubt I'll ever have to worry about this one failing like the oem one did!!!

    Top notch product from a top notch guy. You can't buy anything better. It's not always the price that does it for me. Customer service is worth more than finding a product for a lower price. Paul knows how to treat customers. Period!
