Which drop in filter is the best value, performance and quality? Are all of these re-usable? There are 3 performance ones (that I know of at least) availaible;

HKS Super Hybrid Filter (green in color)
Spoon Racing Filter (yellow in color)
K&N (orange in color)

One of the biggest questions I have is has the Spoon filter been Dyno'd (without other mods) to support thier claim that the stock air-box is best even over a CAI?

Thanks in advance for everybody's input

Cheers!

 

I've used K&N filters on all my cars.....and they worked fine.

 

I actually had a K&N FIRPK2 on my old vehical, I was pretty happy with it.

I just don't know which way to go with the Fit, I can't seem to find any information regarding the actual performance benifits of drop in filters and how they might compare to CIA and SRI's.

Here is a snippet from the Spoon filter:
"The Spoon air cleaner is a drop in replacement of the stock Honda filter. Spoon recommends that due to the design of the VTEC engine, the stock intake box be retained to maximize throttle response."

What does that mean????? Is this just a bogus statement or is it true that a drop in filter is going to provide a better power gain than any CIA or SRI?
.

 

The real reason behind the drop-in filter is pretty much for: SOUND.

You want performance......gotta look somewhere else.

 

And don't forget there is a Mugen drop in out there too. I personally have a HKS drop in on my RHD crx and i love it. I am going for the Mugen one for my Fit though.

 

Right, I missed the Mugen. It is a re-usable one I believe.

Yeah I know a few people who track thier cars with HKS filters, they swear by them. I have heard the only disadvantage is they get very restrictive once they get dirty, then again that is probably true of any filter.

Anyway, my conclusion from everything I have read and looked up is that the drop in's provide an increase of about 2-3hp and a slightly better fuel consumption average pretty much across the board. I have yet to find a single article or dyno that proves one is better than the next.
I would say that the K&N is probably the best deal price wise and maybe even better because it is re-usable. The advantage over other intake systems being (with numbers I have not found to support this by the way) they will give your car a slight advantage in throttle responce over CAI's and SRI's (not power). haha, and sound is probably pretty subjective

It seems to me that the major advantage seems to lie in large bore CAI's which can yeild as much as 7.5hp gain (Injen's claim a least).

UPDATE (06-11-2007):
LOL, after all that research I ended up going with a Fujita CAI anyway.

 

I'm running a Simota replacement in mine. It's reuseable oo.

 

Hold up, Is my Spoon drop-in reusable? I assumed that it was, there

wasn't much information on it on any website so I assumed it was like K&N

 

Cant go wrong with K&N

 

wouldnt the oil in the k&n clog up air sensors?

 

Only if you OVER oil the filter, which you're instructed not to do.

 

Has anyone written a review of the spoon drop in filter yet? Any dyno's for the spoon? I'm considering a drop in filter for my fit.

 

Matt, the Spoon filter is not reusable....just FYI

 

howbout the blitz one? i have an A/T and usually if i put something with too much flow i lose low end, i have the OEM sports muffler right now

 

I think the spoon filter is rated at 200,000km. Butt dyno sensed a slight increase in torque in first and second gear

 

I am using the aFe Pro Dry. It is washable and oil free. Seems good quality and low hassle.

 

I plan on using a K&N drop-in type. My question is: Does this void the warranty? Has anyone tested the setup with and without the resonator, the little extension to the air box?

 

That resonator is insignificant, the resonator underneath and to the left of the airbox itself is where all the restriction is, the only way to overcome it is to block off the hole from inside the airbox.

 

Makes sense. I will have to take a look this weekend thanks.

 

For a little while I used duct tape to block off the hole. If you take out the filter it's in the bottom right corner of the airbox. Definately an improvement on sound but with the stock filter I doubt I had any gains. However the tape would never stay for long and it started leaving residue so I stopped and just left it the way it was until I got an SRI.
