Hi Bob,I installed a Vanistan Oil Cooler on my 2.1 WBX, which came with replacement ducting.I still have my original that you can have.It's 19 cm inches long and 7 cm in diameter.If it will work for you, I'll ship it to you, no charge.Kind regards,Mike M

 Anyone have a source for the flexible air duct that runs up the right rear
pillar from the air box to the air intake snorkel?  I changed my air filter
and found bits of paper and tinfoil from the duct deteriorating on the
inside.

Thanks for any suggestions,
