Osakakev Posted June 4, 2023 Share Posted June 4, 2023 Hi, I want to replace the air filter on my 06 JDM as it has been on since my purchase (3 years ago) and not sure when it was originally installed. It’s an API brand but can only find replacements in Japan. Do I need to use the same brand? I can’t tell if it’s a cotton or stainless? I’ve attached some pictures Thank you in advance!

Jack94 Posted June 4, 2023 Share Posted June 4, 2023 If you're going to spend the money replacing the filter have you considered other options? It looks like it'd just be sucking in hot air so a proper CAI or the original airbox with a decent drop in filter would be better performance wise?

Osakakev Posted June 4, 2023 Author Share Posted June 4, 2023 To be honest I haven’t as I have zero knowledge on so any suggestion would be appreciated! Kev Quote Link to comment Share on other sites More sharing options...
Jack94 Posted June 4, 2023 Share Posted June 4, 2023 I think it's proven that you can't really beat a standard Rev-up airbox with a good drop in filter when it comes to performance. However some people swear by CAI kits, which look great but they never really appealed to me due to how much effort they are to fit and then get to the filter when it needs cleaning/replacing. Also they're a lot lower down so more exposed to water etc. The gains/losses are pretty marginal so if you're happy with the look/sound of the cone filter you've got now I wouldn't worry about it too much, just giving you more ideas to consider.

Osakakev Posted June 4, 2023 Author Share Posted June 4, 2023 Thanks Jack appreciate the reply. Yeah happy enough with it at the moment and car is definitely on the loud side. Can I just replace it with any cone filter or does it need to be a HPI one? Quote Link to comment Share on other sites More sharing options...
ShortPaul Posted June 5, 2023 Share Posted June 5, 2023 Hi mate,like Jack said ,I would also ditch the cone filter and put the OEM air box back in with a decent drop in filter😉 Quote Link to comment Share on other sites More sharing options...
Osakakev Posted June 5, 2023 Author Share Posted June 5, 2023 Thanks Paul. Do I need to make any modifications to put the original back? Car has some expensive mods so surprised they would have changed it if original is better unless it was just for sound? Quote Link to comment Share on other sites More sharing options...

Quite possibly, it may have been remapped with that cone filter on and switching back to an OEM setup even with a decent drop in filter could upset the car / map as you'll be changing the air / fuel ratio Truthfully, I'd be surprised if the above happened as others have said, the gains would be marginal but it's something to be aware of. If it were me, I'd probably be looking for a decent branded cone filter, they're all roughly the same and do the same job Quote Link to comment Share on other sites More sharing options...
Osakakev Posted June 5, 2023 Author Share Posted June 5, 2023 Thanks Olly. Yeah probably do what you said but just found out my Greddy oil cooler hoses are leaking so will put that to top of the list Quote Link to comment Share on other sites More sharing options...
