davey_83 Posted January 15, 2017 Posted January 15, 2017 It's approaching that time again, do I go with the Japanese £20, French £10 or British £5 filter? Or does it not make a difference either way, but I'm not looking to lower the oil pressure. Cheers David Quote
Sargara Posted January 15, 2017 Posted January 15, 2017 Save the money and get a magnetic sump plug instead, that's the best improvement when changing the oil 1 Quote
KyleR Posted January 15, 2017 Posted January 15, 2017 I went for the K&N filter because it has a hex head onto for easy removal. Out of those, the HKS probably has a finer filter than the other 2. 1 Quote

Ekona Posted January 15, 2017 Posted January 15, 2017 Hexhead filters ftw. Otherwise I usually get a Mann filter or OEM. Alternatively I'll simply pick the biggest one that'll fit, as more filtering capacity is really what you're after. IIRC the Subaru ones are usually a good size, or the Vauxhall ones. Quote
davey_83 Posted January 15, 2017 Author Posted January 15, 2017 K&N filter with the hexhead was a Godsend on the SR20DE as the access was terrible, however on the VQ35 I don't really see the benefit. Quote
GMballistic Posted January 15, 2017 Posted January 15, 2017 Personally I would just get the OEM one for the Zed. Getting a magnetic sump plug though is definitely a good idea as Sargara mentions, ...just make sure if you do get one that it's got a powerful magnet otherwise that's a waste of time. 1 Quote
SHEZZA Posted January 15, 2017 Posted January 15, 2017 I've got this magnetic sump plug davey. http://www.350z-uk.com/topic/92915-gold-plug-magnetic-sump-plugs-now-available/page__hl__sump 2 Quote
chirag1988 Posted January 15, 2017 Posted January 15, 2017 I've got the Greddy magnetic sump plug - it's bloody strong! Can be a bit tricky getting it back into the sump as it just wants to a stick to everything Other than that I just use a Mann oil filter. Never had a problem getting the filter off by hand - "Iron Grip" 1 Quote
monkeybrain1234 Posted January 16, 2017 Posted January 16, 2017 Happy to be shot down here but why bother with magnetic sump plugs? My reasoning being that really high end engines, Ferrari, Porsche, buggati, none of them see the need for putting a magnet on the sump out of the factory. Adding a £20 magnet on exotic engines would hardly be difficult to justify if there were any benefits. My guess is there are no benefits hence why every manufacturer is not putting them on. Quote
Olly350z Posted January 16, 2017 Posted January 16, 2017 Because for 20 quid it could potentially save anymore damage being done. It did on my old Honda when the oil pump let go, caught a lovely nugget. Got a mishimoto (spelling) on mine and im pretty sure it got the same pull pound for pound as the moon. Relatively small sumps on zeds make for catching any nastys quite easy Quote

Because a lot of our cars are roughly 10yrs+ old and over the years tolerances change. From new when everything is still perfect I agree there's probably not much benefit as the running in process is there to help. Quote

Relatively small sumps on zeds make for catching any nastys quite easy I see both points however I am still not convinced. With all the R&D and tech that car manufactures put into engines, if they felt there was "any" benefit to adding a magnet they would have I am sure. Sorry for being a cynic Quote
davey_83 Posted January 16, 2017 Author Posted January 16, 2017 (edited) Manufacturers use them for gearboxes and differentials, I guess car makers leave the collecting of the swaft for replaceable oil filters. It's like oil catch cans, we all know the benefits but they're not standard fit on performance cars. Edited January 17, 2017 by davey_83 1 Quote
