Started servicing today.. What purpose does the foam and grate on the underside of the lid for the airbox serve? Can it be removed?

I'll prob replace the crappy paper filter that was in there with an Apex panel.. So the better flow passage the better.

Cheers.

I would hazard a guess it for sound deadaning (got to somewhere) I dont see any reason why you cant remove it, but why not just leave it, it shouldnt be doing any harm...

If you have a look at the inlet of the lid you will see what I mean. Nissan put so much effort into the flow path design of the snorkel and then screw it up at the end with his lump of foam!

I'm thinking rip it out and maybe pop rivet a thin piece of angled stainless in their nice and snug.. Or just remove.. and leave

What does this POS do!... As soon as I get a definative answer its gooone..

Opinions pls..?

Took mine out on saturday.

made no difference to sound.

only plus side for me is that I could see ow much dust was in it and dirt particles under it.

so in went the vacuum cleaner tip.

Also blocked the bov bleed hole.

just take it out.

it's just for sound deadening.

    • Yeah I've had too many issues with knock off's on the BMW's. I don't want to do a job twice or more because the parts are shit.
    • I read this and thought "ah! I will do this scissor jack on the tow point thing!" I just use my floor/low profile/costco jack and lift the car up by the tow hook itself, then slide jack stands under. Never thought about using scissor into floor jack combo :p
    • Well, my new WMI system took much longer to finalize. I actually missed my dyno appointment last Friday and lost my 150$ deposit. I'll be going back in the next week or two.  To sum it up. I only kept the AEM tank from my old setup. I replaced the AEM pump with a higher flow/pressure ProMeth 30GPH pump. I also swapped over to a 6AN low pressure feed line to the pump from the tank. There's also a pressure switch you cannot see on the pump high pressure line.    This is feeding 6x 200CC direct port nozzles and 1x 500CC Pre Throttle body nozzle. All fittings are Swagelok, because well why not. I also have a 300PSI pressure sensor up front.    I now have my Haltech ECU controlling everything. I start my pump with a basic relay at 5PSI and deadhead it. I then PWM a 3000CC methanol Injector to control flow starting around 10psi. The pressure switch in the trunk, along with my tank level are safeties before I ever get to 10PSI, and then I use my pressure sensor upfront as a secondary safety to cut the WMI and corrections in case the injector blocks or a line ruptures.  Wish me luck on the dyno!    
    • So, I'm back with bad news. There's no jack long enough on this planet that will reach the front subframe. If by some chance there is, it would weigh 200lb's.  I purchased a long reach jack... The damn thing weighted 120lb's and was massive. Didn't even come close, was still short at least a foot. It was a pain, but I brought it back. Next I decided HA! No problem, I'll get an Extra long reach jack. Well, I couldn't lift the box... It must have weighed 160LB's and luckily there was an open box in store. I took measurement and was still nowhere close.  Sadly I've lost hope and have accepted defeat. 
    • Thanks for that tip, niZmO_Man. I think the battery is OK. It's quite a new one, but I'll check. Last time I needed a new battery, everything electronic was fine, except that there wasn't enough current to turn over the starter. I decided to order one of the partial AV system translation CDs from Car Audio Workshop in NZ. That might have some effect, or help me diagnose the date problem. 🤞
