Oil catch can and K&N air filter

Installed a mishimoto oil catch can and a K&N filter. I will see how much oil it catches on the first oil change. Also the filter made a tiny improvement made the turbo a hair louder. Way better than stock. Worth the $40.

Is this an Si? Also did you have to buy different hoses?
Yes it’s an SI, I had to go too the parts store for the outlet hose. The one that it came with didn’t reach. Also I don’t know if you can see in the pictures but I put a sleeve on the gas line that is behind the can just to protect it from rubbing on the can.

You got the sleeve from the parts store as well? Thanks for the info!
Yes just split the left over vent pipe and used that.
How is the catch-can doing?
Haven’t opened it yet. Going to when I do the oil change, that will be soon. I’ll post pictures of it and an update.

I'm having a really weird issue and hope you can chime in. So with the can installed I get this weird random rattle almost sounds like its coming from the dash and only hear it in the car. Checked under the hood and everything looked fine, I kept the can installed but removed the hoses and connected the stock PCV-Manifold line and the sound completely went away. Hooked the can back up, rattle is back.

Does yours make some weird noises? I'm wondering if the can is acting almost as a sound amplifier for noises in the crankcase at certain RPM]

Thank you! I just got a cheapie baffled can like I have in my MX-5 and going to install this weekend, I didn't want to "mod" the car but after some research it just seemed like a good idea for Turbo DI engines especially
