Perfect for a custom job
I purchased a K&N FIPK for my AP2 Honda S2000, but decided that I did not want to use the provided K&N filter and stick with the OEM Honda filter. They did not have the 3.5 to 3" coupler/reducer at PepBoys so I ordered it from Amazon. It arrived in a very nice box and included two quality clamps. I cut about an inch from the Honda OEM filter's neck and used the coupler to attach it to the K&N intake tube. It is a quality product and it seems to hold up pretty well so far. I had to adjust the clamps once, after the engine bay was hot and have not had to tighten them since. If I need any more intake couplers/reducers I will not hesitate to purchase from Spectre.
