rtbiscuit Posted June 16, 2011 Share Posted June 16, 2011 As you may be aware, i am sorting out a conversion kit for the pre facelift air boxes and some of the people on there would like a performance filter at the same time. I was interested to see if anyone else would like one as the more ordered the cheaper i can get them. and if so what would people like/willing to pay. i have put a selection up and the kind of price they are currently available for on the internet. some are more expensive than others. and was this a put off factor, or do people not mind the price as long as its good. my primary choice for the conversion kit is the Do-Luck filter, it is apparently the best filter for the 350Z and offers the maximum gains for the car; so for those going for the conversion kit i though tit would offer the best chance of maximum gains. but at the end of the day its only going to be the difference between 1 or 2 BHP. This is an extract about the jap performance magazine test: In an independent ‘shootout’ between 7 panel air filters, Do-Luck out-performed all of the competition! In the coming edition of Japanese Performance magazine there will be an interesting feature on a group-test of panel filters... Conducted at Scooby Clinic, using their Dyno Dynamics rolling road, air intake temperature remained the same (16-17°C) and two power tests per filter were taken. Filters tested were: K&N ITG Pipercross Green Cosworth Do-Luck All filters were tested on a standard 54-plate Impreza WRX STi 2.0-litre, which was originally fitted with a standard panel filter. The results? The pre-oiled Do-Luck foam filter Gave a max BHP of: 297.7 (12.9 BHP extra over the stock filter). Its nearest competition giving 10.4 bhp... “Japanese Performance found the Do-Luck filter produced the best performance gains, throttle response and power curve characteristics. According to actual test data, the best value for money filter is Do-Luck and it also produced the most amount of additional BHP†Quote Link to comment Share on other sites More sharing options...

Chris`I Posted June 16, 2011 Share Posted June 16, 2011 If they are all within 1-2HP of each other I would question which of them gives the best filtration as they are all giving pretty much the same level of flow. Did they measure filtration too? Quote Link to comment Share on other sites More sharing options...
notfub Posted June 16, 2011 Share Posted June 16, 2011 Can the Do-Luck filters be cleaned? If so, how much are the cleaning kits and where would we get them from Quote Link to comment Share on other sites More sharing options...

Did they measure filtration too? i'm trying to find the actual article, but can only find reference to it. lots of other forums talk about it, but not found the actual article. i also added the BMC on there, it is the most expensive, but they make great stuff, and very few people seem to know they exisit. they build a lot for motorsport and F1 teams. as for cleaning the do luck ones, you can use a K&N filter cleaning and re oiling kit and you can get them from halfords.

Ekona Posted June 16, 2011 Share Posted June 16, 2011 What's really needed (and I apologise for the hijack in your thread Rich, will remove it if you like), is to do a dyno run with a Zed both with and without an air filter in place to gauge exactly what you could reasonably expect from a performance filter in terms of power and filtration. Someone must have done a comparison at some point, maybe Abbey or Redline over here? Or someone in the US? Quote Link to comment Share on other sites More sharing options...

rtbiscuit Posted June 16, 2011 Author Share Posted June 16, 2011 on a side note; i was chatting to pipercross yesterday and apparnetly they used to make the filters for nismo, learn something new every day, Quote Link to comment Share on other sites More sharing options...
Jez @ H-Dev Posted June 16, 2011 Share Posted June 16, 2011 I did some testing with standard versus Cosworth filter and it made no difference to power on a relatively unmodified engine (I think we had plenum spacer, de cats and remap). I'd advise against an oiled filter - the afms don't like the oil much, going on past experience with other Nissan hot wire AFM cars. Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted June 16, 2011 Author Share Posted June 16, 2011 thats why i also like the BMC panel filters as they are a dry filter. although on the K&N website they acutally state that there is no link between oiled filters and MAF failure http://www.knfilters.com/faq.htm#27 Quote Link to comment Share on other sites More sharing options...

I've had 2 sets of filters that are oiled, Pop charger on my 350z which did 65k+ miles (filter cleaned and re-oiled every 9k miles) and on the Stillens on my 370z. In total about 75k miles and no problems. Quote Link to comment Share on other sites More sharing options...
andlid Posted June 16, 2011 Share Posted June 16, 2011 try and find out which filter does the best airflow but also the best cleaning, reason I went with apex back in the day was that it was giving ENOUGH air but also cleaned the dirt. This also depends on the rest of the breathing mods that has been applied to the engine, so for a more or less standard Z you don't need as much free flow air. Again I kinda agree with the dyno testing on this one. Quote Link to comment Share on other sites More sharing options...

In the world of BMWs, the BMC filters are highly regarded. I also had a BMC performance panel filter in my BMW 330ci M sport, bought it for £45 Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted June 16, 2011 Author Share Posted June 16, 2011 i would say the BMC would be a good option, but i'm not sure people would want to pay that much for a filter. The Do-luck stuff is well respected, and offers a good option. i could probably get pipercross at the cheapest price, and as said before they used to make stuff for nismo, so nissan obviously liked what they were doing. but people don't seem to go for it and i'm not sure why. i've tried to pick brands that other traders on here aren;t doing so as not to step on toes etc. i know you can't please everybody, but there must be a happy medium etc. Quote Link to comment Share on other sites More sharing options...
Ekona Posted June 16, 2011 Share Posted June 16, 2011 If it were me and my money, and I was putting money towards the only thing that stops all the crap and dirt getting into the single most expensive item on the car, I'd be buying the best full-stop, and especially if we're only talking about a £20 difference. You'd have to be bonkers to risk anything less IMHO. Quote Link to comment Share on other sites More sharing options...

rtbiscuit Posted June 16, 2011 Author Share Posted June 16, 2011 cheers Protegimus, good info; i have now made a filter decision; just waiting on some suppliers to get back to me on price and then i'll post up on here. Quote Link to comment Share on other sites More sharing options...
andlid Posted June 16, 2011 Share Posted June 16, 2011 I'm in agreement with Ekona on this, please make sure it's filtering dirt and give a happy medium between airflow and cleaning. Dirt 0 is a must. Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted June 17, 2011 Share Posted June 17, 2011 No HKS filter was used.......... Some one care to supply all the filter's ( minus the HKS ones I will suplly that) I supply the dyno free of charge. Let me know , turbo cars are notoriuos to give un relaible figures due to heat soak , even a Zed will need cooling to give the same AIR INTAKE TEMP ambient figure doesn't really make a different as long as it is around 30+ degree's in the dyno room. Let me know if you want the test done on our Dynapack? we can even log the ECU data to get a fair test. Mark Quote Link to comment Share on other sites More sharing options...

rtbiscuit Posted June 18, 2011 Author Share Posted June 18, 2011 i am going to be hopefully supplying the Apexi panel filter; they are an arse to track down but i have a few contacts and some prices due back soon, and they shouldn't be far off the prices we were looking at above for other filters. where exactly they fall into i'm unsure until i get all my quotes in. the reason for my choice; well i've always been a big apexi filter fan, i custom fitted one to my typhoon induction kit on the Zed and i used them on the MR2. and the reason i like them can be seen in this article here. http://www.mkiv.com/techarticles/filters_test/2/ its an old article but it goes to show how good apexi stuff is, excellent filtration as well as good BHP gains. i know its from a cone comparison, but the panel filters are made of the same stuff, and its a product i would fit in my car, without question.
