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.

      Thanks for your insight, it being basically useless will impact my decision for sure. I thought it may help the engine breath better I guess. But then again, I have also been told that tuning an RB20DE is also not worth it. Exactly, we follow EU Regulations. There is a bit more leeway on older vehicles. My Porsche 924 came without a cat from factory and managed to pass, they still mentioned that I have quite high emissions on it though.

      My apologies, I stand corrected. Thanks for registering to mention this! And thank you for actually reaching out to the council to clarify. This is the sensible thing to do and the opposite of what I was alluding you were doing. I may have seen too much outrage and hate being fueled on the internet and it has made me a somewhat cynical old man. Sometimes it is easy to forget that there are real people behind websites and accounts. In my defence, CarExpert and CarExplore do read quite similarly at a glance. I shall try and do better in the future. (Please stick around to get the latest scoops on dealing with old Nissan shitboxes )

      Don't bother. The poor little RB20 doesn't make enough gas flow to challenge the flow capabilities of even the littlest cat, and you won't make any extra power, and all you'll do it soot up your rear bumper. Plus....is Malta not runing under Euro regs?

      Hey Daniel, sorry to hear that and thanks for posting up for us at a really hard time I only knew SmoothLine through the forums, we never met as we are based in different states, but when he was most active on here he was quite a while back so not many of the current crowd might remember him. I am pretty sure he was active in the Queensland SQU club but that is defunct now too (times are changing and we are all getting older). Farewell SmoothLine!

      Turns out depending on whether the car was equipped with TCS or not there are different signals coming to the dash, meaning there are different speedo clusters.  Wired in a speedo calibrator box from aliexpress and now works fine.
