[Tigers] Air cleaner & horsepower

Thu Jul 5 10:23:49 MDT 2012

Different manufacturers make different sizes, if you are fortunate to
live near a Summit Racing, Jegs or someplace with a great speed shop,
you can practically build your own design from separate pieces,
It has come a long way in five years, I had my first one hand made to
fit a GMC Motorhome with a warmed over Olds 455.  It made a huge
difference in low end torque and sounded rather cool for an RV.
All of my street cars run K & N kits, they pay for themselves in the
cost of not using replaceable paper filters alone.
