Filthy Fill Posted May 25, 2003 Share Posted May 25, 2003 Hi All, Having recently purchased a Jap Import K reg Auto Twin Turbo Fairlady Z I decided to fit an Apexi Power Intake Filter. Unfortunately when I offered up the filter to the air flow sensor the bolt pattern did'nt match. After re-drilling a couple of holes I got the filter on, however when I took her for a test drive all was well on " normal " driving but when I put my foot down the revs just died, foot off the gas revs came back, foot down revs died. I was not able to solve this problem and had to put the stock air box back on. Any advice would be greatly appreciated. Phil. Quote Link to comment Share on other sites More sharing options...
SRRAE Posted May 25, 2003 Share Posted May 25, 2003 Who did you buy the filter from? It should have fitted perfectly as mine did. Did you reset the ECU when you put the filter on? You should have so the ECU can relearn how to work, especially with an increased airflow. Also make sure the wire to the MAS (Mass Airflow Sensor) was correctly plugged in and it wont hurt to clean the contacts while it was unplugged.

Guest scoops Posted May 25, 2003 Share Posted May 25, 2003 mine also fitted perfectly Quote Link to comment Share on other sites More sharing options...
Filthy Fill Posted May 25, 2003 Author Share Posted May 25, 2003 I didnt realise I had to re-set the ECU (new to this) is it easy to do ? Bought the filter from Japan, E. bay, didnt come with adapter kit and not specific for 300zx. Phil. Quote Link to comment Share on other sites More sharing options...
SRRAE Posted May 25, 2003 Share Posted May 25, 2003 Disconnect the battry for 45 mins. Try leave it for an hour and then connect it up again. Also when you put it back on check the connection to the MAS as what you discribed sounded more like a MAS problem Stuart Quote Link to comment Share on other sites More sharing options...
Filthy Fill Posted May 25, 2003 Author Share Posted May 25, 2003 connection to the MAS. MAS ? Quote Link to comment Share on other sites More sharing options...
Smithy Posted May 25, 2003 Share Posted May 25, 2003 Seeing as it's not 300zx specific as the bolts didn't line up, sounds to me it's leaking air where it joins the AFM, take it off and smear some sealant where it has all the holes, refit to AFM and wipe clean any excess. smithy:cool: Quote Link to comment Share on other sites More sharing options...

SMW1 Posted May 25, 2003 Share Posted May 25, 2003 does it look like this ? http://www.300zx-mods.co.uk/Induction.htm Quote Link to comment Share on other sites More sharing options...
Filthy Fill Posted May 25, 2003 Author Share Posted May 25, 2003 Looks exactly the same, I used your site for reference,cheers, didnt get any brackets though. Quote Link to comment Share on other sites More sharing options...
Guest andrewwarren Posted May 25, 2003 Share Posted May 25, 2003 If its the same size as my Apexi air filter it needs Brackets. The filter would be bouncing around all over the place surely!!!!!!! Mine came with 4 brackets-also fits exactly!!!! :D Quote Link to comment Share on other sites More sharing options...
Filthy Fill Posted May 25, 2003 Author Share Posted May 25, 2003 I could make brackets without a problem but i dont think this will sort out the revs dieing off when the pedal put down. Quote Link to comment Share on other sites More sharing options...
