Use our One to Four splitter together with our Four to One Mixer and create wild parallel signal chains! Use our Buffer/Splitter and run 2 x One to Four Splitters to have 8 parallel paths!!! This device features a unity gain buffer on each output for maximum punch and clarity. These buffered outputs have a flat frequency response with a high 1 Mohm input impedance and a low 100 ohm output impedance. This means that your signal won't lose any quality and will sound just like you intended. Even long cable runs will be no match for the One to Four Splitter.

Perfect fit and high quality.
Size: (Pack of 1)
Good product, not much to say. The product arrived quickly, looks to be of high quality construction, fit perfectly and took me only a couple of minutes to install. I love it when a product is no frills and delivers as advertised. I've used various filters from K&N before and have always had very good success with them so I will be buying more of these for sure when the time comes.

More power, slightly lower (8%) MPG.
Size: (Pack of 1)
Installed on a 2.0 liter Subaru Impreza. I drive up/down the I5 in california 3-4 times a year. For those that don't know there is about a 200 mile flat stretch where everyone runs at 75-85mph. With various filters (FRAM, BOSCH, Subaru OEM), I would consistently get 29.8 mpg. Once I installed the K&N, I could feel the car pulling with a bit more power, but I noticed that I was getting about 27.5 mpg. Totally worth it as the impreza is a little under powered and I don't drive many miles (6k/year) but if you are putting a lot of miles on your car, you may want to have more mpg.
