Hi guys,

I am new here.
I have been looking to buy CAI in buy/sell forum for couple day already. It is very hard to find. So I am thinking just to use drop-in filter with OEM air box. I did "better flow mod" with it, thank you RX-8 club for instruction.

I need recommendation for replacement filter for OEM air box.
I did the search already but no result.

What brand would you recommend? K&N, Green Filter, R-Magic, ITG or any other brand? (I saw ITG banner here)

I found out that K&N drop-in is popular here. Any reason to go/ not to go with K&N?

Also what material would you recommend? Cotton, Polyester, others?

Thank you in advance,
Tony

K&N for sure.

I can ship you one for $49.

get it from CRH, u get best service.

K&n w/ your flow mod and did you remove the vfad? that will give you cai sound, i love mine!

I have the green drop in air filter and it works fine same as the k&n air filter. Just remember to get the cleaning and re oiling kit.

i have the K&N drop in with the better flow mod and the RB ram air.. it works really nice. and just a tad bit more hp

Thank all of you for your answer.

I went to Mitsubishi Eclipse G4 Club for same question too since new filter would also used for my girlfriend ride. (Most people recommend CAI…. I think Eclipse seems to respond very well to CAI, unlike our 8)

People there recommend Green so I did some more online research and found reviews said that Green is better that K&N because Green does not have any wire mess to support its structure, therefore gives better flow.
Any comment about this?

How about our site sponsor? Despite, I never heard of ITG brand, I found out that ITG filter is quite popular too. Their filters are used in many F1 and WRC car.

I still have no clue for any JDM product like R-Magic.
I could not find R-Magic website and distributor.

All brand above cost around the same $50 +-10. So no price differentiate here.

Oh! Also clear OEM air box mod too. Have anybody try that?

I don't see any rx8 application for the Green drop-in filter on their site...any leads?

Corksport sells them.

R-magic works great, I have this one and I am very satisfied. Notable sound difference in high rpm plus it's dry, no need to oil and very easy to clean.

Before forking over much extra $$ for a fancy filter for the OE box keep in mind this will do absolutely nada for performance over an OEM filter. There is so little restriction in a good clean OEM filter to be virtually immeasureable.

Anyone who promises otherwise is well.. hasn't measured the OE filter.

cool air box.

can you post some more pics !!

i think its the material that helps.

plus a K&N filter last the life of the car , if maintained properly of course.

i decided to cut the cost of a drop in filter and put it towards a CAI

no regrets

i bought my k&n drop-in used on the forums. already cleaned and re-oiled.

$15.

:lol2:

I'm using the Green filter that I bought from Corksport. In terms of airflow performance, it's more or less the same as K&N (remember the OEM filter is quite good to start and more airflow from the aftermarket filters has negligible effect). I decided on an aftermarket filter vs OEM because the aftermarket in the long run will save me money! The reason I went with Green is because the plastic border molding of the filter has a more intimate fit with the airbox so particles have a lower chance of sneaking around the border. Also the fact that it's a cool GREEN color.

I think the drop in filters are somewhat over-rated, especially in a daily driven car. The primary function of an air filter is to filter... go figure. The amount of extra flow you'll see going with a K&N or something similar is pretty much negligible, but I've seen tests (not specific to the RX8's filter) indicating that they filter out less particulate than a traditional cotton filter. A lot of people run them, and it's probably not that big of a deal, I just prefer having a little peace of mind vs. the 1/2 HP gain at redline... plus I like playing devil's advocate ;)

I have a green filter, wih No regrets. the only thing I have to compare it to us a stock filter, adn ell no butt dyno impression really, btu along with removing a single scren adn the baffles, I e a bit more sound, and perhps a bit more air.

o me, the biggest benefit is acually that for under 200% the price of an OEM filter, you get a lifetime filter. Any performance gains are a benefit beyond that.

a CAI on this car typically are ll sound, and in MANY cass degrade the perforance. I plan on getting an AP at some point, and the word on the street over there, is that NA, stock is king.

Thank all of you for your answer.

The only advantage I know is the theoretical one that there's no danger of over-oiling and fouling the MAF (I have no idea how much of a risk that really is with the Green or K&N).

Whether it filters better, lasts longer, or flows better, I don't know.
