Don’t pay the labor fee. Do it yourself
Much cheaper than having the dealer install it or even from the auto parts store. Easy to install, took less than 5 minutes.

Perfect fit
2015 Honda Fit, does what it’s supposed to. Super easy install. Don’t pay someone $30 to do it at your next oil change. Easy DIY
