Here we have the heat shield which comes with most FIPK applications. These are included in the system so that the air intake won’t be gathering in too much heated air from the surrounding engine bay. The design fits the 2001+ Civic well, and does give a good separation of the space between the filter cone and the engine bay. Although you should realize that unless it’s a totally separate compartment, you can’t expect the heat shield to completely block off the heated engine bay air. Still, the location of the filter is right next to the combustion chamber, so it’s a good idea to have this separation.
Remember that colder air equals denser oxygen molecules, which means more oxygen to combust, which equals to more horsepower. That’s the basic concept behind most cold-air intake applications, although they’re also a bit overblown and hyped.
From the snapshot to the right, you have another view at the multilayered cotton filter cone, and the intake tube along with the filter adapter. Unlike most cone filter in other intake applications, the opening end of this K&N filter cone is noticeably wider, and is reduced into the intake tube size via the well designed filter adapter, which helps fit the filter cone onto the intake tube snugly.
The above picture shows the fully assembled FIPK kit for the 2001+ Honda Civic. It’s straight forward and simple: larger filter element, less restrictions, better intake tube flow tract = better throttle response and more horsepower – or so K&N claims. It’s easy to claim that, but sometimes without a back to back dyno (stock vs FIPK) we can’t see objective results. Unfortunately as of now there’s no other independent dyno graph on the FIPK for the 01+ Civic, besides the one provided by K&N. Click here to see the dyno from K&N.
K&N claims a not-too-outrageous 4.8HP gain at 6,200 RPM on a 2001 Honda Civic EX 5 speed manual transmission model, which is close to the stock peak horsepower RPM range (6,300 rpm)
If you look carefully at the data provided at the graph, you’ll see that during the second run the ambient temperature level has increased by 2 degree Fahrenheit, and it was done 21 minutes later (time it took to swap out stock intake and install FIPK). So maybe on a run of same ambient temperature and less engine heat, perhaps the FIPK can yield a better HP gain on the dyno, although that’s all speculation.
