yeah I have heard some reports that the oil can gum up the AFM sensor... But I think there is more chance of this being caused by blow-by...

Just get a $30 simota or 3A Racing... It is all the same material and often the filters with the extra filter piece in the middle can give even more flow! They are supposed to be cleanable but for the $30, just throw it away and get another one!

If you really want an apexi, put a sticker on it... :laugh:

Oil on the AFM wouldn't be caused by blowby because the AFM is upstream of the rocker cover return.

I'd rather have an oiled filter beause they should filter better. Better to clean the AFM once in a while than to let a whole lot of dust into a motor over a long period of time. Btw, I believe 90% of oiled AFMs are due to over oiling of the filters. You really only have to use a minute amount!!

      Foreign debris, physical shock, boost leak, could be anything honestly. The danger in taking all the timing out of a tune/hitting the R&R corner is that even if the engine doesn't detonate your turbo is taking a lot of abuse from high EGT. Also, even if nothing goes wrong it is a journal bearing that is spinning at 100k RPM on boost. Eventually it goes through enough cold start/pressure cycles to wear it out.

      Possible option to replace central computer 370 V36

      By Vee37 · Posted

      I kinda accidentally saw this, and was interested, but It actually seems to replaces the whole center computer, using the existing screen and buttons. AND it may only be for a G37 and not compatible with a Japanese 370. So its not for me, but someone else may be interested to look into it. Its about $680USD. If I am understanding it right, it basically replaces/installs and android pc that integrates with the existing screen. But I could be wrong. https://gromaudio.com/vline/ The video I first saw was the following, with very little and unclear details.     Even if your not interested in the system, the video on their site was pretty comforting in showing how simple the whole centre comes out

      Import insurance in 2025

      I’m with Shannon’s for all 5 of our cars. Agreed values seem fair, premium price is okay. ($210 ish a month, all comprehensive).  Have claimed once with them for a not at fault claim with another car where my car had no damage. Was one call after the incident and an email after. Deemed not at fault so premium didn’t go up either.    I have called up and spoken with people who are not familiar with certain cars and didn’t agree with me on value or let their personal vehicle preferences effect the call. But called back later and got someone else who was more agreeable.
