我就知道KN
pipercross和itg没听说过？{:4_649:}
除了KN，PP，ITG其他是陌生点。
Pipercross空气过滤器 冬菇头测试
Pipercross空气过滤器由海绵介质制作，非常类似于ITG空气滤清器器，我们的预期自然就和ITG对比上了。事实上，它比ITG的产品具有更小的阻碍限制，1.14kPa的最大压力说明了这个问题。而且已经非常接近Jetex棉纺过滤，两者之间只有边际的差异。虽然ITG单元不是最好看的，整体上是稍微大一点，这也是最有可能是它具有稍微好一点的气流的原因。
限制（KPA）1.14
价格：85英镑

日常KN就够用了～
As not everyone wants to remove their standard airbox, we also restriction-tested a few standard panel filters in exactly the same manner as we did for the cone filters. The entire airbox assembly was fixed to the end of the rig, and we increased the flow rate incrementally and recorded the pressure increase to see which offers least restriction.
The first thing to note was just how restrictive the standard assembly really is, so much so that even with the rig running flat-out we couldn’t achieve the 6.75m3/min flow rate we used when testing all the cone filters. That wasn’t a major concern, however, as Tony had calculated that a standard Ford Fiesta ST only requires a maximum of 5.5m3/min, and as the same flow rate would be used for all three tests, we could still make a direct comparison.
It was also worth noting the most restrictive cone filter we tested had a pressure of 1.21kPa at 6.0m3/min, whereas the best flowing filter within the standard airbox was 2.56kPa.
Overall, we have to conclude that if you want maximum performance from your engine, a large cone filter is definitely the way to go over a standard airbox.

只要看图表就好了~·

限制数值越大越好？
结论也就不翻译了~·
只说说标准的进气箱加纸质空滤的设置是多么令人难以置信的严格，这个标准气箱的配备让发动机被有效地勒死，原装一个令人难以置信99.75％的过滤确实恐怖，但你会看过，这是非常严格的确实，而ITG只有77％。
好吧，跳过文字~·直接看排名：

限制既阻碍~·数字越大阻碍越大，通过效率越低~·gochinway06；） 不过有可能过滤会好~·但这也要看面积~·
