The Green Filter

**Chad** · 12-02-2012, 01:53 AM

Shomare and I were browsing around the 2012 SEMA show about a month ago, and we stumbled a crossed The Green Filter. What we were so impressed with, was the air flow that the filter had, versus other brands. So I filmed a short 15 second product demonstration. I knew that I would be getting one of these filters for my car as soon as I saw this, and I wanted to share with everyone. Pay attention to the little ball..

So, after the demonstration I asked what the filter was for the Focus ST.

Filter Number: 7159
Product Website:
https://www.greenfilterusa.com/store/7159

from website about the product...

Maximum air flow for more power & torque
Improves engine efficiency (better gas milage)
Washable and resuable filter is environmentally friendly
Super strength to withstand engine intake pressure
Highest quality control on rubber injection molding
Pre-oiled so they are ready to install right out of the box
Extra pleats used for maximum surface area
Woven cotton to insure the greatest flow of air
Will NOT void vehicle warranty
Limited lifetime guarantee
Superior filtration
Race proven
Made in the U.S.A

So The Green Filter is a cone filter, and it is steel mesh construction. Since installed I love it. The sound is great! You can hear the turbo, and there is a very nice whoosh sound when the air flow is sucked, then stopped. It makes the engine a little lower, and the exhaust a little louder. It really sounds cool when you are "on" the car.

Sound

There is no way for me to determine if the filter makes the car faster or not. I don't feel a difference, the only way is to dyno. Every filter says that they increase mileage, and power. Someone needs to test this.

I have not seen a decrease is mileage, if anything a modest increase. But I don't have any data to back that up. I know my car doesn't get worse mileage. In the past, other cars I have got worse mileage with a filter. This is a great enhancement to the car, without doing a complete Cold Air Intake.

Install

Take 4 bolt screws out.

Pop the cover off

Pop the filter out. May take a bit a of work.

Install by slipping the filter over the hose intake, with the clamp. Do not over tighten clamp, or the filter will pop off. Just get a firm grip and it will not go anywhere. Mine has been installed for a month with no problems.

Reinstall cover and enjoy!

Very cool demonstration video, definitely makes it easy to compare vs. K&N and stock. But performance aside, it just sounds awesome. To me, the price of the filter is worth it to have that sound. It would be interesting to see if there were some gains though. Great work!

Yes, that sound yesterday was very cool indeed!

Question... on your car you had the round piece on the end of the box open... does that just pop apart of did you have to cut it open... sorry, if you told me yesterday... being an old FART i suffer from CRS...

That round piece is part of the filter. The green filter doesn't have it covered.

I could kick myself. I had just ordered a K&N otherwise I would have purchased the Green Filter.

The K&N doesn't change the sound like the Green Filter does and the Green Filter obviously flows better than the K&N as seen in Chads video.

I'm a diehard skeptic so my first thought after reading this is that I've seen videos of some magician guy walking though a glass windows too. "Seeing is believing" doesn't apply to videos.

Looks to be a safe, simple, & cheap mod. Thanks for the review. Also, I can't get enough of the BPV sound lol

So my question is; with the increased airflow, how can we be sure that particles that would get caught in other filters aren't getting through to possibly damage the engine?

"4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cotton’s microscopic strands. The nature of the cotton allows high volumes of airflow, and when combined with the tackiness of the oil creates a powerful filtering media that ensures engine protection."

I took this from K&N's website. However, virtually the same idea, in some variation, would apply here I'm assuming

Exactly the reason for the question. K&N makes that statement, but with the green filter flowing air so much better, can they have the same filtering capability?
