I recently had to bring my car back to the dealer for a blown 02 sensor so I put my stock airbox back in.

I forgot how much low end torque my car had!
Car pulls off the line so much better than with the Franken Intake.
She actually feels a lot more responsive too!

but from a roll.....The Frankencar Intake makes a huge difference.

 

I had to borrow my dads stock I30 3 weeks ago. The difference between a highway run of 60-80 in both cars is like night and day, give it to frankencar.
