rayaapp2 Posted May 28, 2010 Share Posted May 28, 2010 The first air filter I ran on my RB was a K&N 3" cone filter. With only a few hundred miles the filter collapsed. I was forced to walk into the closest auto store(think it was Kragen) and buy a "Spectre" universal cone filter. The filter was suppose to be temporary. Well it has been a year. Ive cleaned it several times and it has turned out to be not so bad. Its time to grow up though. Im seriously considering installing a typical square filter in a custom box up front like a stock Nissan filter for a newer car. Id go for a stock 280Z air box if the intercooler wasn't in the way. Ive thought of all sorts of air filters. The HKS style or whatever brand floats your boat mushroom foam filter are not really suitable for daily road conditions though they flow really well. I am unsure one of those mushroom filters would even fit. Im over the cheap filters and the K&N filters. They have been a constant headache and worry. The deal is that I would like it to fit in front of the intercooler somewhere. Im worried about blocking airflow to the intercooler and radiator. The current cone filter hits and rubs the hood when the hood is closed. Im not fawn of it moving and rubbing the intercooler either. Its not a good situation. I regularly see bugs stuck in the cone as well... I wonder is sand could blast its way through. There isnt much room on either side of the intercooler for a filter or box. So here is where I am open to suggestions opinions. What ever I use must be able to stand up to the suction and be able to filter while still flow well. Im sure there is a way to determine what filter by air flow, filter size, and filter mess flow, but Im lost there. I can get measurements for anyone willing to get involved in detail. Thanks guys Quote Link to comment Share on other sites More sharing options...
Ricky Ricer Posted May 28, 2010 Share Posted May 28, 2010 Go with the apexi. Flows the best and has the best filtration. Don't ever use HKS. Quote Link to comment Share on other sites More sharing options...
10cjennings Posted May 29, 2010 Share Posted May 29, 2010 (edited) Why exactly are you against K&N? I know you said you're filter collapsed but was that because it was being squeezed into a space it wasn't really designed to fit? I've never heard any complaints on them collapsing (as you hear with old paper style filters when they get clogged with dirt) Edited May 29, 2010 by 10cjennings Quote Link to comment Share on other sites More sharing options...
rayaapp2 Posted May 29, 2010 Author Share Posted May 29, 2010 My last one collapsed on itself, but I also dont want to run an oiled filter... Any over oilage at all and you risk damaging the MAF sensor with the oil. Oil isnt metered when applied so its a guessing game at best depending on your experience. Its just not worth the hassle for me. Ray Quote Link to comment Share on other sites More sharing options...

Midnight-280Z Posted June 3, 2010 Share Posted June 3, 2010 I run a Nismo filter, the same ones that came with the 350Z Nismo Intake System. Never had it collapsed on me..I'm almost 100% positive that it's also made by K&N. Apex filters are also really good as well. I would avoid HKS filter as other people have stated. I'm really curious as to why your filter collapsed, I'm running the same motor and almost the same filter. My filter is set-up differently though, it's still in the engine bay behind the radiator Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted June 9, 2010 Share Posted June 9, 2010 Apex filter for me, bolts straight to the MAF! Quote Link to comment Share on other sites More sharing options...
jakeoster Posted June 9, 2010 Share Posted June 9, 2010 (edited) I can also attest to the Apexi filter. I've put a fair amount of miles on mine and it has been great thus far, plus you get the convinience of simply bolting it to the maf. I believe the HKS one is only for like racing, not for daily/road use. Edited June 9, 2010 by jakeoster Quote Link to comment Share on other sites More sharing options...
rayaapp2 Posted June 10, 2010 Author Share Posted June 10, 2010 Almost Unanimous! APEXi. I assume you all are talking about this one? It appears to be similarly priced to other high quality filters out there. ~$50-$60 for the filter Would you guys be willing to post a part number or link to where you bought yours? Then there is the matter of install. Those of you that installed this filter did so in the engine bay and attached it to the MAF. I would want to put the air filter up front where the current one is. I think I will have to remove the torsion bar hood spring and install the filter so that it points nose cone down. Quote Link to comment Share on other sites More sharing options...

My link I think Kragen has this little Specture MAF to filter adapter that might work for you if your not going to mount the filter to the MAF.

240Z_Master Posted July 15, 2010 Share Posted July 15, 2010 Off topic... does anyone know if the Apexi filter is washable of some sort? Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted July 15, 2010 Share Posted July 15, 2010 AEM dryflow filter. Quote Link to comment Share on other sites More sharing options...
jakeoster Posted July 15, 2010 Share Posted July 15, 2010 Off topic... does anyone know if the Apexi filter is washable of some sort? No, it's not designed to be washed. It's a zero maintenance filter meaning you don't have to oil it or anything either. You can take it off and use compressed air to give it a cleaning if need be.

240Z_Master Posted July 16, 2010 Share Posted July 16, 2010 I'll look at what bolts up to the MAF... my old filter was just in a bad position... I actually like the Apex a lot... but it's probably time for a replacement anyway since the dang thing is 4 years old Quote Link to comment Share on other sites More sharing options...
