Hi guys,

Long time admirer of all the cool stuff being done to the tig!

With regards to the Golf R intercooler, is this simply plug and play with the tiguan hoses? I contacted a shop here in Perth and they told me that an extra bracket was needed as well as modifications??

It depends on the generation of the Tig. Older 125KW Tigs had MK5 GTI style intercooler so some modification to the piping is necessary.



As you can see that style intercooler accept hoses with a special metal clip. In that case you may have to remove the metal clip and modify the hose or use an adapter to connect to the Golf R intercooler.

But later generation Tiguans and high spec Tiguans ( 155TSI or 147TSI) have MK6 GTI intercooler and you don't have to do any modifications to install a golf R intercooler.

Apart form that Golf R/ S3 intercooler is direct bolt on to any Tig except 118TSI Tigs.

Welcome fellow Tig modder

I've done this mod on a 2011 125TSI and it's definitely worthwhile if you can get your hands on a good second-hand unit. There's a few that come up from time to time from people with S3/Golf R that upgrade.

As Ramee says there is some modification to the pipework that is needed. If you can get the pipes with the Golf R intercooler as likely if they have upgraded the intercooler they will have done the pipes also.

I think from memory I used the Golf R hose on the outlet and modified the Tiguan hose on the inlet (the Golf R hose is too short). If you cut off the aluminium connector from the stock Tiguan hose it will slip over the Golf R inlet. Then all you need is a couple of hose clamps to secure it - job done!

Of course there's the other part where you pull the front end off the car and disassemble so that you can pull the old intercooler out and slip the new one in... so once you've done that modifying the hoses is the easy bit!

Awesome, thanks Ramee and Tigger, hopefully get it sorted before it heats up over here!!

The only other "gotcha" I can think of is the orientation of the spigot fitting that plugs into the turbo outlet pipe. It's a good idea to compare the orientation of the two tabs as they can vary. You can do this as step 1 of the changeover - just remove the undertray & pull the hose off. It's not a show stopper as you can buy a new spigot fiting on ebay. If you need a link let me know (will take some digging).

If you're after a Golf R intercooler I can put you on to a guy in Victoria. I just bought some parts off him & he mentioned he had a Golf R IC that was cluttering his garage. price will be around $150 I'd guess
