whats up guys my girl has a 2012 civic lx with a r18z1 motor. wevebeen looking for some aftermarket parts and cannot find any without breaking the bank.

were looking for coilovers and a cold air intake.

i can install the coilovers but i was wondering if anyone has any ideas how to make a mass airflow sensor for the cold air intake. i dont want to buy a $300 k&n intake because my money is tight. any help on a custom MAS would be great!!!! thanks guys
