aFe has designed a high-performance drop-in air filter for the IS-F that allows for more airflow and better throttle response compared to the stock filter.
best of all, it doesnt need to be oiled so no fouled MAF sensors and it is really easy to clean.
this is probably the easiest mod to do for your IS-F


Cleaning is really easy too. You can even wash it under water and use virtually any type of detergent to remove the debris and grime off the filter. and at 99.4% filtration level, you dont have to worry about dangerous particles getting through

"Quotation Fingers in the air" more airflow compared to the stock filter.

Do you have airflow tests measuring cfm's with the aFe vs Stock?

AShepherd

great question

this chart should tell the story about the air flow difference over stock filters



aFe Pro Dry S Filters offers up to a whopping 306CFM over stock!!!

More potential airflow doesn't mean more power in this car. Here is a link to my dyno results of the AFE dry.

I have been using aFe filters in my ISF as well as my previous cars. I'm am very impressed with their build quality and construction. While power gains can be debated, I like the filters for their ease of use and serviceability. They will last a lifetime and are easy to clean.

AShepherd

yes it is definitely debatable as the airflow around the car on a fixed dyno does not represent real life situations
but at the very least, there is money savings since it is so easy to service and last virtually a lifetime

good dyno test though, always good to see some data. I never fully take dyno tests seriously for air intake swaps though. the better test is probably quarter mile times

Thanks for the reply BUT I was referring on being more IS-F specific. The chart is based off of stock car filters not the F's.
DO you have info on the F's oem air filter cfm rates vs the aFe? That would be my hook to buy one, thx.

I am a little confused on this. The quote excerpted from the aFe literature (I am assuming) references the filter as being an "oiled" filter while the description below is touting the benefits of it being a dry filter. I think they offer both but any clarification here would be helpful.

AShepherd

so the chart was apparently for the IS-F stock vs the wet version of the Pro filter





http://afepower.com/catalog/30-10167/NPA.pdf

with the Pro Dry S being around 420CFM, i would say it ties with the stock on the high-end but the type of media on the Pro Dry S would give it a light more edge at the low-end

you could go wet and get a lot more performance (66% more airflow)

Until it fouls the MAF right?

UberNoob

haha usually MAF gets fouled when oil gets lathered on too much during filter maintenance
the factory pre-oiled amount of oil is not enough to get into the MAF sensor and onto the wires

but there is still definitely a risk

i personally got the Pro Dry S for my GS300 for the sake of being safe

I've got 50K miles on mine. I cleaned it at 30K and it was very easy. You save $35-$40 (the price of an OEM filter) every time you wash it yourself.

what site can i order aFe drop infilter?

aWorkOfArt

Check out Luis from l-tunedparts.com

Here is the link to the filter: http://l-tunedparts.com/product/?id=3246

It's best if you call first and ask him if he has any in stock, and incase you were wondering, they offer package deals with a JoeZ intake tube. GL and happy modding bro!

Chillz

Thx and do you think the afe drop in filter is better than the f sport drop in air filter? or which one would you prefer?

and im looking for 2014 is 350 im having a hard time looking for parts
