  • Aftermarket Air Filters Work?

    Jason Fenske has facts!

    Do performance air filters actually work?

    Sean Szymkowski; Jan 28, 2019

    Air filters are one of the easiest and quickest components to swap out for an aftermarket part, and plenty of companies claim their design will increase horsepower, torque, and improve acceleration.

    Do they? Jason Fenske of Engineering Explained is here to answer that question. For the test, he used a Subaru Crosstrek and four different air filters. One is the original air filter that came with the car after thousands of miles, the second is a new OEM filter from Subaru, the third is a low-cost replacement from CarQuest, and the final part is a K&N air filter.

    Fenske tested each filter with a dyno run and then measured acceleration with a VBox to see if any data learned from the dyno translated to the real world. Up first was the original air filter, complete with dust and bugs.

    The Crosstrek laid down 158 horsepower and 137 pound-feet of torque with the original air filter. Note: Fenske said the dyno measured high since the Crosstrek only makes 148 hp at the crank. However, the test is still valid because it serves as a baseline for the other filters. Fenske explained in the past that dyno numbers may not actually be something to brag about, due to some quirks.

    Next up was the clean OEM filter and the car returned 160.1 hp and 137.4 lb-ft. Minor increases with a clean filter, to say the least.

    Moving along, the CarQuest filter helped the Crosstrek produce 163.3 hp and 140 lb-ft of torque. The aftermarket filter made more power, but Fenske wondered if it's also actually filtering less in general.

    Finally, the K&N air filter promises to deliver more horsepower...and it did. The Crosstrek produced 164.3 hp and 142.5 lb-ft of torque.

    With the data on hand, do the minor performance increases from the aftermarket filters stack up in the real world? In short, yes.

    Jason measured the 20-60 mph sprint and the 45-60 mph sprint. The latter is to show any top-end performance gains. While the dirty and new OEM filters were nearly identical in their sprints (9.01 seconds from 20-60 mph and 3.61 seconds from 45-60 mph), the aftermarket air filters improved on that performance. The CarQuest filter registered a 20-60 mph sprint of 8.91 seconds and a 45-60 mph time of 3.56 seconds. The K&N was, again, the best of the bunch. 20-60 mph happened in 8.81 seconds, and 45-60 mph took 3.49 seconds.

    Yes, the aftermarket performance air filters do work. But, don't expect oodles of extra ponies to suddenly show up when mashing the throttle. Check the video above for more details.

    Im now of the belief its not worth the money...or the time.

    used to be there was a scoop of some sort that would allow the air filter take in air from outside the engine compartment more easily and drop the temperature of the air being brought into the engine.

    its been so many years I forgot the formulat but ill guess and say for each 10 degree drop of air intake temperatures you would pick up 1 percent of hp that would not always show up on stationary dynos even with fans on...

    the automobile engineers are so effective in this day and age...its just not worth the money for an aftermarket air filter or intake.

      GM tests its air filters to insure that for a 100,000 mile life span for its motor, that the amount of particles that get into the motor do no interfere with the motor’s life. Do aftermarket companies do that?

      While there used to be easy horsepower left on the table by OEM’s, not so recently. For example, for the first time the 7th gen Corvette motor gets its air taken not from within the engine compartment, but from a cooler location, coming through the passenger front wheel liner area though the side of, and then into the engine compartment in a sealed intake system.

      While this is a K&N picture with its intake system, including its filter for the C7, the blue arrow show the air coming in through the side of the engine compartment into the OEM air filter, then within a sealed tube into the MAF, then into the motor.

        Cool photo John and I agree...the engineers do a great job paclaging their high performance products to the next corvette Ill leave the mechanicals stock..

        the corvettes are so powerful. So fast...these days...the increase or potiential increase isnt worth the time or momey.

        better to leave it stock..

        the few extra ponies possibly made arent worth the hunt.

          I believe nothing is free. The more the power, the less the actual filtering.

            That is the key, I believe. I seem to recall a test from many years ago on motorcycle filters that demonstrated the K&N does, in fact, allow more particulates to pass through the filter. If they returned a 20hp gain on a 150 hp motorcycle many would consider that a worthwhile tradeoff. But for a couple of HP? Not worth it to me.

              As everyone is stating above, no worth it for me either.

              If it was that much of a HP improvement while still keeping the particles out of the engine, Chevy would have been selling my my Z51 package as possibly a 500 HP vehicle instead of 460 HP if there were mechanical improvements that could have been made to the air filter to boost overall HP and serve the purpose as an air filter.

                I do wonder why Jason didn't dyno-test the one obvious remaining scenario... with no filter installed at all, and thus no restriction.

                I expect it was because he didn't want to overload and damage the engine dyno, given all that excessive HP and torque...

                  Here is a Bad Example of trying to double your air intake as it will be drawing air in after it passes through the hot radiator. The proper way to increase your air intake is to double or triple your filtering size with the same filter media that was designed for the vehicle. The filter media should be capable of filtering out 20 micron particles at least. Intakes should also be ducted to a cold air intake source and be completely isolated from the engine compartment. K&N Filters site tries to say that air filters are not rated by microns but by efficiency of airflow. B.S. You also have to have their filters sprayed with the proper oil for them to filter out smaller particulates. Which most people don't do regularly.

                    Having a cold air intake box like this one will not allow any heat in from the engine compartment and will allow double the original airflow. However placement is usually an issue as most engine compartments these days are crowded. The two openings have to be ducted to a fenderwell or outside opening.

                      Here is a good video on dirt entering your engine. And intake system.
