This has been happening for some time now. I have a 99 ex, with a d16a (d16z6) and I kept my obd2 ecu. I used my y8 intake manifold and y8 injectors. It runs good. At normal operating temperature, with a normal idle, the cars pulling in a lot of air. Also it's summer so is it ok if I use 10w/30 until winter?

 

What do you mean it's pulling a lot of air?

 

RonJ!!!!! It's been a while! It's just sucking more air through the intake, you can actually hear it like a hissing/ sucking noise. I know it's hard to write how something sounds lol but it's definitely sucking a lot of air.

 

it's a normal side effect of a ram air intake. don't worry about it. and yes 10w-30 is fine
