Review part 33-2277
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.

I'm impressed! I purchased part number 33-2277 for my 2003 Honda Accord EX V6. While my gas mileage and power was more than sufficient before, after the installation of your product, my gas mileage increased from a consistent 25 mpg in the city and 31 mpg on the highway to 26 mpg in the city, and 33.5 mpg on the highway at 75 mph! (with the AC on) Throttle response is even sharper with the throttle-by-wire as factory installed. My performance figures are as follows before and after the installation of your product 0-60 7.0 seconds stock, now 6.87. Quarter mile times dropped from 15.5 seconds at 92 mph to 15.1 seconds at 94.2 mph. Top speed on a closed race track increased from 138 mph to 143 mph. The only additional change that I completed with the addition of your product was to switch my engine oil to synthetic. My mechanic believes that my horsepower likely increased from 240 hp to 245. Great job in your product development. Keep up the good work!

I just thought I would share this short story with you about a k&n air filter. Aprrox. 3yrs ago I was at the auto wreckers in edmonton alberta looking for a mirror for my old beat up 1990 honda accord. I noticed a dirty oily old air filter laying on the ground underneath another similar year honda accord. It pretty much been parted out . I wasnt even sure what kind of a air filter it was but it looked well constructed so I took a chance on it and bought it from the wrecker for a $1.
When I got home I did some investigation and indeed find out it was a k&n air filter. I kinda compared it to what was in my 1990 honda accord and it looked very similar in size. I purchased a k&n cleaning and oil kit and cleaned it up,dried it out and sprayed it with the oil as per instructions. It came up like brand new. To make a long (sorry) story short I have had this in my car since. My accord has 394000 kms on it and it has never run so good. I used to have an engine light symbol go when it got cold but since I have had this filter in there it has been perfect. It is dec 22/2012 now and I have asked for a k&n air filter for my 2008 toyota tundra 5.7 litre for christmas. Thanks k&n and merry christmas
