You Save 16% ($9.00) Improves Horsepower and Acceleration Filters Out Harmful Contaminants Fits 05-09 GT and 05-10 V6 Stock Air BoxNow you can improve your 2005-2009 GT and 2005-2010 V6 Mustangs performance with a K&N Drop-in Replacement Air Filter. Simply replace your stock restrictive paper air filter with a new high flow K&N air filter and feel an increase in horsepower and acceleration while still providing excellent filtration.Filters out harmful contaminants. The K&N Drop-in Air Filter filter's out harmful contaminants with it's unique layered design. K&N Air Filters are made up of layers of specially treated cotton gauze that are sandwiched between two epoxy-coated aluminum wire screens for durability. K&N uses a specially formulated grade of oil to treat the cotton gauze layers which causes a tackiness throughout the cotton’s microscopic strands creating a powerful filtering media that ensures engine protection. K&N designed this Air filter to be a direct drop-in replacement for the stock 2005-2009 GT and 2005-2010 V6 Mustangs air box, with no cutting or trimming required.

This air filter came in and is high quality! I recommend this air filter all the way! Best route for CAI Look, in all honesty, no matter what someone says, air flow is air flow. The stock set up is perfectly fine if you install a K&N filter.

With the installation of K&N drop in filter and removal of the inline carbon filter will it be necessary to retune or can I reboot compter No retune needed when reusing stock intake tube.

Show 1 more answer I need this answered (0) How much will this increase horesepower? How much horsepower will I gain and will it make my new flow master American thunder muffler sound better? What is the difference between this and a cold air intake system? I have a 2006 mustang v6. Not a huge gain, but it is noticable. Plus its the last filter you will need to buy! Installation Time: Less than 1 HourI now get 24 mpg instead 22 with the restrictive factory air filter.

I recommend this 100%. Oh and also, for those wondering about the horsepower gains, I do not believe you will feel a huge difference, however the roar of the engine slightly heightened acceleration is worth it to me! Bang for your BuckThe amount of air you gain with an aftermarket CAI is honestly nominal to what you can achieve with a simple filter swap. Plus, just cut out the front bottom of your stock airbox and you just created a CAI for the price of the filter. The stock air intake is specifically designed to fight off heat. Do this test, put your hand on the tube of an aftermarket CAI after running all around town and feel how burning hot the pipe is...that heat is heating your air going in. Do the same thing with the stock set-up...waayyy cooler than a CAI set-up. IT'S THE TUNER THAT CREATES THE POWER, NOT THE CAI YOU BOUGHT. I highly recommend going with the K&N modification good product, stock filter was all dirty and im glad i replaced it. First of all the product was just what i wanted, it does give you alittle bit more pull on accelaration.

I feel like i might have pick up a little more hp, not that much just alittle. very very easy to install just pop off clipps put in and you are ready to go. The reason i decided to buy this is i didnt know which cold air intake i wanted yet,so i got this for the mean time. If you are looking for alittle extra horses and better acceleration then just buy it, you will not regret it. Took about 10 secounds to put in, easy to do. Maybe it's in my head, but I felt more power right away. Second car I've had K&N in and never any problems. You'll let your engine breathe better and boost fuel economy by about 1-2 mpg. Never saw above 23mpg with v6 but got 24.8 on my first tank with this air filter combined mpg!! This product is alot better than the factory filter but you will notice little or no power gain from this item but did notice a slight increase in MPG'S This was just what I needed to go with my new flowmaster exhaust. It gave it an extra little pep and even made the flowmaster sound better.

Makes me happy and makes my care happier. K&N Drop in air filter 2010 V6 Great really can feel the difference quick shipping too which i love everywhere else takes weeks got mine in two days This is the 1st time I have tried a replacement air filter. It seals good as expected. I figured if I buy the cleaning solution and reuse it more than once - It probably will be cheaper in the long run as well as better air flow performance.HEPA Filters and ULPA Filters Information Show all HEPA Filters and ULPA Filters Manufacturers High efficiency particulate air (HEPA) filters and ultra-low particulate air (ULPA) filters are air filters designed to trap a vast majority of very small particulate contaminants from an air stream. Air filters must satisfy certain standards of efficiency — most commonly those developed by the US Department of Energy (DOE) — in order to qualify as a HEPA filter. The US standard (DOE-STD-3020-2005) requires that a HEPA filter be capable of removing 99.97% of contaminant particles 0.3 μm in diameter.

Most standards also specify that HEPA filters must feature minimal pressure drop and maximum airflow when in operation. A filter's percent efficiency can be calculated using the simple equation below. E = percent efficiency D = downstream concentration (of contaminants) U = upstream concentration (of contaminants) Particle Size and Filtration Method While the US HEPA standard usage of 0.3 micrometer particles to describe efficiency may seem arbitrary, particles of this size are actually the most difficult to filter, rendering them a kind of "worst-case scenario" reference particle. The reasons for this difficulty in filtration are described below. HEPA filter media is made up of countless randomly-arranged fibers which together form a dense mat; when air flows through the filter, the media captures and contains contaminant particles throughout its depth. A fibrous filter's media as seen through an electron microscope. Filter fibers trap contaminants using three primary methods:

The three filtration methods described above (plus an electrostatic method). Understanding these three methods makes it clear why particles around 0.3 micrometers are most difficult to filter. Particles less than 0.1 micrometers are easily trapped due to diffusion while particles larger than 0.4 micrometers are trapped by inertial impaction. Particles between 0.1 and 0.4 μm are therefore too large for effective diffusion and too small for inertial impaction and efficient interception, so that the filter's efficiency drops within this range. By specifying a HEPA filter's efficiency at 0.3 μm, standards bodies are really describing a variant of the filter's minimum efficiency. A HEPA performance graph, showing the steep drop in efficiency around 0.1 μm. While HEPA products designed for industrial, military, and government applications are explicitly certified, some cheaper consumer air purifiers and filters are marketed as "HEPA-type" and are often touted as capable of "removing 99.97% of dust and allergens" without specifying particle size.

The growth of these marketing devices has led some manufacturers to use the term "True HEPA" to describe filters and purifiers manufactured and tested to DOE or EN standards. Ultra-low particulate (or sometimes "penetration") air (ULPA) filters are closely related to HEPA filters but are even more efficient. ULPA filters are specified to remove 99.999% of contaminants 0.12 μm or larger in diameter. The chart below shows the overlap in the capabilities of ULPA and HEPA filters. Image credit: Sentry Air Systems European Standards for HEPA and ULPA The European Union standard for both HEPA and ULPA filters — EN 1822 — classifies filters into different classes depending on their efficiency. All EN 1822 specifications are based on a filter's ability to trap and contain the most penetrating particle size (MPPS) particular to the filter. The MPPS is typically determined by a laser spectrometer or electrostatic classifier. European filter classes and relevant specs are listed in the table below.

Note the radical difference between the European and American definition of HEPA efficiency, particularly that the EU standard permits HEPA filters with efficiencies as low as 85%. Table source: AAF International HEPA and ULPA filters are used in applications requiring very efficient filtering of airborne pathogens which can cause aggravate asthma and cause allergies or disease. These filters are also useful in manufacturing environments which require very clean air. Standards are particularly important to the manufacturing, use, and testing of HEPA and ULPA filters.
