[mkiv] Factory oil cooler alternatives

[lance]

Teflon is way overkill for engine oil.  It's also not preferred because when
it kinks it gets permanently damaged.  The rubber lined hoses are fine for
this application, but even braided stainless is way overkill.  There are
lots of Kevlar wrapped hoses that are lighter, stronger, and not nearly as
likely to slice your hands to ribbons if you accidentally find a broken
strand.

Thanks Oolan.  You were right, I just called a local hydraulic shop and they
do have the 10an Teflon SS braided hose. $7.50 per foot.  They have up to 1
inch diameter.

the turbo/manifold and you'll be fine.

For all future plumbing, I plan on going with crimped teflon lines. 
Yes, they're available in larger sizes, just not from the race shops. 
Look for the hydraulic shop people with bulldozers, garbage trucks, etc.
use. Also ask the local small nascar teams where they go for plumbing. 
If they don't get big enough, ask at the big truck repair shops and
aircraft hangars. In my central IL location, it's cheaper to have a
shop make me lines than it would be to buy AQP or similar parts from
Summit or Racer Parts Wholesale.

One thing about pro-lite, it's not necessarily more flexible than SS
braided, or if it is you don't want to have it bent that much when
installed. Also, last I checked pro-lite must be crimped so be aware of
tool costs. Ask Earl's what the replacement interval is for pro-lite,
they probably have a recommendation for the teams that use it.

I wanted something with a Teflon lining, but I've only found it up to 8an
size.
