I would like to know if anyone has made the low cost
performance mods made in past issues of Miata mag.  The mods I
saw included advancing the timing to about 14 degrees BTC,
using Spitfire plugs, changing to a better air filter, and
perhaps a few other minor things.  I'd like to know if anyone
can comment from experience on these changes.

I am particularly interested in the timing change.  What are
the disadvantages of making this mod?

Timing change was easy to do, and made the car slightly - but
noticeably - more "spunky."  My wife noticed it too.  I now seem to get
an occasional knock if the revs drop down too low from a standing
start.  Otherwise, no drawbacks I've noticed.

QUESTION:

I would like to run an intake snorkel from the airbox to the front of
the car to draw in cool air.  I would close off the original snorkel.
However, I can't find a good place to draw the cool air - the front end
of the car is just too crowded.  There's a 3/4" space in the driver's
side of the radiator. but it's pretty tight.  Has anyone else tried
rerouting the intake - without buying the Jackson Cold-Air kit?
