Update on my July 15, 2003 submission to K & N on my results

To Whom IT May Concern,
I must say that I am very impressed with your product. When I installed part number 33-2277 on my 2003 Honda Accord EX V6, I initially tested its performance on a closed track. Well after some additional testing recently, something interesting was discovered. On a certified Dyno machine, the stock wheel horse power and torque increased from 204.5 hp and 180.7 ft/lbs to 216.3 hp and 191.4 ft/lbs! The flywheel horse power rating at 240 hp is likely 250 hp using the standard calculations. What was most interesting is how the power curve changed. The engine developed a flatter torque curve with a peak at 4,750 rpm as opposed to the 5,000 rpm stock reading. The same results followed with the horse power delivery. I don't believe hype, so the math results tell the story. After using this product for 90 days, I re-tested the performance results at the same track, and here is what happened:

0-60 7.0 seconds stock

0-60 6.87 seconds K & N installed July 2003

0-60 6.63 seconds K & N after 90 days


1/4 mile 15.5 seconds @ 92 mph stock

1/4 mile 15.1 seconds @ 94.2 mph K & N installed July 2003

1/4 mile 14.8 seconds @ 97.8 mph K & N after 90 days


Top Speed (certified with a calibrated and properly operated radar gun)

138 mph stock

143 mph K & N installed July 2003

146 mph K & N after 90 days


Gas Mileage (measured with the on-board Honda Navigation and mileage calculators)

25.0 mpg city, 31.0 mpg highway stock

26.0 mpg city, 33.5 mpg highway K & N installed July 2003

26.4 mpg city, 33.7 mpg highway K & N after 90 days

Note: When the testing was being completed, the gas mileage for that day was 17.2 mpg. Obviously, this type of driving was not usual and customary, and thus was not included in the overall gas mileage calculations.

Additional testing was conducted and across the board increases in performance in 5-60, 20-40, 30-50, and 0-100 mph tests were very apparent. I have discussed my findings with some Honda experts and they say that part of the results should be credited to the on board computers for the car. They say that engine computers have likely remapped the fuel/air mixtures to take advantage of the new levels of air available in the intake as a result of the use of your product. This makes sense to me. My neighbor installed a K & N filter in his BMW M5 and ZO6 Corvette and saw similar performance increases. I hope that anyone who reads this testimonial understands that these results are facts, that should be easily repeatable with other vehicles.

The air filter works well in my son's BMW 330ix.

I bought this filter to replace the stock one in my 2009 BMW. The K&N filter fit perfectly and didn't produce any error codes with the electronics.
