looks good. I might pull the trigger on this

 

I got those installed and everything went well for quite sometime now. Until one day I went to do some PM check and looked inside the intake tracts and found out a lot of dust throughout the intake tracts!!

I'm living in a dusty area but still, a good filter would not let this amount of dust just ingested by the engine. I had to clean all the intake pieces with soap and water to get rid of the dust. So if you live in a dusty area or not obviously. you need filter wraps around them or do as I did and buy Apexi filter heads. Haven't seen any dust inside the tracts since the're installed.

The Z1 kit in general is very good in design and fitment but the heads are unknown and has no branding and I wouldn't risk running these anymore.

Check out my thread regarding other issue but has all the info related to this one (post #26) : https://www.myg37.com/forums/engine-...-c-is-off.html

^^ Interesting but not surprised. I would recommend any upgraded filter over a no name any day.
