Aftermarket Coolant System & Fuel Line Hose Kits
2000 TT Quattro 70k miles and hours of frustration but still loving it!!
Heat is an issue with rubber parts under the hood. Check with Steve at the ModShack, he has a replacement firewall gasket that is around $20 that reduces underhood temps quite a bit.
Honestly, I'd look at Audi for that. My Dealer is frequently competative on cost and his parts are usually better than aftermarket.
YMMV
