Hi Everyone.  From personal experience in our '91 Miata, and our '87
Golf Diesel, the K & N filter replacement cartridge has done wonders
in fuel economy, top end performance, and filtering of dirt.  These
filters work well, and never have to be replaced, just regularly
cleaned with K & N's recharge kit annually.

I have never experienced any higher operating temperatures than
normal filters, and the engjnes breathing is dramatically improved.
Starting off the line is also much better.  I have recommended these
filters to my friends, and they have also reported the same results
whether in a GTI VR6 Golf, Aerostar minivans, or a GMC 1/2 ton truck.
 These filters work, and work very well indeed.  A cheap way to gain
extra power, cleaning efficiency, better mileage, and performance.

I would run a K & N in the Syncro but I already have a stock of
Syncro filters to use up first.

Just my own experience...
Harry.
