Subsequently, question is, do K&N cold air intakes really. Depending on your car, a cold air intake system increase efficiency from 3 to 5 mpg, which can help you save considerably over time. But, don't expect oodles of extra ponies to suddenly show up when mashing the throttle. Upgrading your cold air intake system can help make your vehicle more fuel efficient by letting air flow more freely through your engine. Yes, the aftermarket performance air filters do work. 20-60 mph happened in 8.81 seconds, and 45-60 mph took 3.49 seconds. The K&N was, again, the best of the bunch. The CarQuest filter registered a 20-60 mph sprint of 8.91 seconds and a 45-60 mph time of 3.56 seconds. excessive pressure across a dirty air filter can cause a 115 increase in fuel consumption. 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 latter is to show any top-end performance gains. Jason measured the 20-60 mph sprint and the 45-60 mph sprint.

With the data on hand, do the minor performance increases from the aftermarket filters stack up in the real world? In short, yes. You will literally see a fractional, and most likely a gain in gas mileage that you wont even notice (as long as you drive the same as before). The Crosstrek produced 164.3 hp and 142.5 lb-ft of torque.

The aftermarket filter made more power, but Fenske wondered if it's also actually filtering less in general.įinally, the K&N air filter promises to deliver more horsepower.and it did. Moving along, the CarQuest filter helped the Crosstrek produce 163.3 hp and 140 lb-ft of torque. apparently i should be getting 333miles to a tank (without the intake) but since i put the intake on im only getting around 280 (i dont. im only getting about 11miles/gallon city/high way driving. Minor increases with a clean filter, to say the least. I just put in a K&N cold air intake on my 08 tundra 5.7 and am losing mileage rather than gaining. Next up was the clean OEM filter and the car returned 160.1 hp and 137.4 lb-ft.
