Just installed this air filter and it looks great. Slight increase in power. Still waiting to crunch the numbers on fuel economy. I definitely prefer this filter to one you have to re-oil. Overall I'm happy with my purchase.

I HAVE 4 CARS AND THE SPECTRE IS ON 3 OF THE 4 CARS. THE FIRST REPLACEMENT AIR FILTER WAS A K&N . THEN I SAW THE SPECTRE AND IT SEEMED TO LOOK AS GOOD AS THE K&N AND I THOUGHT FOR THE PRICE DIFFERENCE I WOULD TRY IT...OUT CAME THE PAPER FILTERS AND IN WENT THE SPECTRES. I FELT A GOOD POWER FEELING WHEN PULLING AWAY FROM A LIGHT.THE MOTOR SEEMED TO ENJOY THE EXTRA AIR FLOW AND IT TRANSMITTED TO A EXTRA POWER THRUST WHEN THE PEDAL IS HEADING FOR THE METAL. GREAT FEELING!!
