The Apexi super intake cold air intake filter is the clear winner. Power increase was good though, 3rd in this comparison with a 13PS increase It is slightly surprising to us that the foam used in the HKS filter performed worse than even the metal mesh used in the Blitz filter. The dust filter was clearly much dirtier than any other filter. However the power increase with the Blitz was almost the same as the Apexi filter (13.9PS) 5th – HKS Super Power Flow By far the worst filtration performance of any filter in this test. The Blitz filter is made of metal which does not have a good reputation for quality filtration. 4th – Blitz SUS Power Cone Filtration by the Blitz SUS Super Power Cone was worse than Apexi, K&N and SARD but it was not the worst cold air intake filter in the test which was a big surprise. The SARD air filter gave a 11PS increase. Power increase was also lower than the Apexi and K&N cold air intake filters.

Power increase was slightly down versus the Apexi filter at 13PS increase 3rd – SARD The filtration quality of the SARD filter was third behind K&N and Apexi. Power increase was also the highest with a 14 PS increase 2nd K&N The K&N cold air intake filter had the second cleanest filter. 1st Apexi – Best Cold Air Intake Filter The dirt filter from the Apexi Super Intake was by far the cleanest of all the filters in the test. The dirt intake tests were done on HKS Super Power Flow filter, Apexi, Sard, Blitz and K&N cold air filters. These samples were compared to see which filter filtered the best. A filter was place under the neck of the filter to catch the dirt that passed through the filter. Dust was panned out over the filter for a fixed period of time, while air was being sucked through the filter with a vacuum cleaner. Revspeed magazine did a filter test to see which cold air intake filter did the best job at filtering dirt ie stopping dirt from entering the engine. Which is the best cold air intake filter?
