Hi I bought my 300zx and when I was looking at the intake, it had a aftermarket air filter which I'm not sure what it is or if it was installed properly. Any ideas? I think from other pics it is a HKS system but not sure. Maybe an ebay knockoff. Appreciate the help

 

No, I would say it leaks unfiltered air - zip ties cannot seal it right. Also, it looks like it is pressed against a panel. The assembly will not breath efficiently and will rub with road vibration and engine torque movements.

 

thanks but is it worth keeping or change to apex or jwt pop charger?

 

Buy a JWT pop charger.

 

Lol ok I know this if from 3 weeks ago but wow wow wow. I can't believe somebody used zip ties lol. Maybe they used some gasket sealer to make it better, doubtful I know but I would if I was stuck. Agree with Sam...
