the $70 K&N intake system (AE95, 4AFHE engine)

budget builds are my favourite, the K&N cone cost me $50, then spent $20 maybe on aluminum and the 45º PVC elbow.

the intake sounds amazing, better throttle response and fuel economy.

the mounting point isn't ideal, but hey, I made it in 20mins in my driveway... I also want to route bigger "fresh air" piping up to the intake.
I drilled the bottom of the elbow large enough to slip the original rubber gasket in for the intake sensor to pop in, perfect.

after a few long haul trips I've noticed a big difference in fuel economy with the intake and exhaust combo.
I was ratbagging my car on the Coquihalla going around 140kph for a majority of the drive and still averaged 7L/100km.

I am considering making air box for the intake to make it a cold air unit, I'm curious how much fuel economy I will lose doing that...
