K&N factory replacement filter vs K&N cold air intake filter. live data review.

PORSCHE 911 COLD AIR INTAKE BY K & N VS FACTORY REPLACEMENT K&N FILTER

This is Porsche 911 996 c2 air filter system. As you can see the mass air flow sensor is located really close to intake valve and total intake tube is only about 8 inches long from flat air box. having mass air flow can disturb the air flow in to intake.

This is K & N cold air intake system. as you can see mass air flow sensor is located far away from intake valve. long venturi down pipe will decrease temperature and increase air flow. sensor is far out the way so air flow will be lot better at the intake valve. I have tested both system with my live data computer and k&n cold air intake showed more pounds for minutes.

k&n claims 23.8 hp gain.

22.7 lbs torque gain at 5500 rpm.

my test show about over 10% air flow lbs per minutes.

So what do i think?????  I love the way car drives and sound.

you can buy the system around 250.00 to 375.00

Part number is 57-7000.

It seems like amazon has best prices

Just copy and paste the 57-7000  in to amazon search box.

you will see the price compared to auto part stores online.
