Outstanding replacement option for 2025 Tesla Model Y Performance (Pre-Juniper), so much smoother than the OEM wipers. Very easy to replace. They seem very durable after testing on all wiper settings. Definitely keep the windshield clearer without streaks. Seem to also have more stability on mounting compared to OEM option. 15/10 replacement for the cost, can’t beat it.

he Gold Standard in Air Filters

This product works just as intended. K&N has been a leader in lifetime air filters for a long time, and their reputation for quality is well-deserved.

Been a K&N customer for over 20 years.

I use K&N on all vehicles that I have owned. It has always given extra MPGs and extra HPs. Always easy to install, easy to clean and maintain. if you keep your vehicle as long as I do (my last two vehicles, a 2001 Toyota Sienna lasted 18 years, and 2000 honda civic LX lasted 17 years), this filter pays for itself and more! definitely worth the price. I bought one now for my new Honda Civic EX hatchback which I will also drive until it breaks which could be 2 decades from now - imagine how much I will save on regular air filter purchases and extra mpgs. very well worth the price!
