I thought I may as well post here as it's semi related. I ended up going with this air box from R-factory, Aluminium backing plate, fibreglass outer with a knife edged 'egg ring' with steel mesh screen fitted. It's bewdiful  :-* Most important is it will let me run big stacks.

Will the mesh effect air flow into the box, it's similar to flywire only it's stainless steel?

This one is for Alan Fields, what brand airfilter do you use in the 280 airbox? My plan at this stage is to duct it in a similar style to your green 260Z.

Thanks, Gareth.

Well done the R-factory item is a nice unit, tappered like the Prince/Nissan item and as close as you can get in an aftermarket unit.

I'm considering cutting out the mesh, if it will improve the airflow.

Without your suggestion Mike I may have never even considered it, Thanks.

Any sort of material introduced into the intake system will have some effect on flow/performance i guess it just depends how much(if even measurable)

Loose the mesh.
Especially if your running a filter in front of the radiator.

Hi Gareth
I use a 280z filter housing (from the US 280z - S30 body with injected L28)......can be found on Ebay for very little $$$ although shipping can be exy from the US......think mine cost around $50 all up plus another $50 to sand blast and powder coat

Filter is R31 Skyline.....fits perfectly.

That is what I will be running also - and I am yet to purchase a K&N Panel Filter for the factory S31/HLS30 aka EFI Fairlady Z (S31) and USDM EFI 280z (HLS30 - not to be confused with the HLS30 USDM 240z lol)

Thanks Alan.

Mike, I did see uni filter do a washable filter for the R31 skyline, looks to be the same material as their socks.

Looking up the unifilter catalog R31 = TT267-155S a Z31 = TTN-4200S if I lookup a cross reference for the K&N for the 280z (USDM) I find the following.

K&N = 33-2010 (correct for the 280z and Z31 300ZX) this cross references to Ryco A345 which cross references to TTN-4200S

Going backwards from the R31 I get
TT267-155S = Ryco A360 = K&N 33-2031 which as K&N have the sizing on their site is thinner and other dimensions are slightly different

K&N 33-2010 = 35mm H, 270mm L, 156mm W
K&N 33-2031 = 29mm H, 279mm L, 167mm W

I found the message from Alan who confirmed the R31 filter does fit the stock 280z (HLS30)/Fairlady Z (S31) factory housing I must have been blind when I posted that stuff above.

So I will pickup one up soon.

Airbox measurements are roughly: 670mm long, 135mm deep at the front tapering down to 110mm at the rear, 160mm high. Check your engine bay clearance, especially to the strut tower.
