K&N Replacement Air Filter for the 2012-15 Honda Civic Si (FG4)

The Honda Civic has been a sales leader for decades and it has a reputation as a dependable and occasionally, a fun car. With the inline 201 horsepower 2.4L engine at its heart, the new Civic is reasonable in terms of power. The Honda Civic also keeps the famous iVTEC system in place, even rewarding you with a light when you are pushing the engine hard enough to utilize it. While it is often considered a given that your 2012 Honda Civic SI with 2.4 liter engine will last for many years and many miles, it is a fact that you will be paying for a new air filter every few oil changes unless you change to a quality lifetime air filter that is washable and reusable. The K&N 33-2473 air filter is just such a filter. With K&N's performance heritage behind this product you can also expect to see a 1-4 horsepower increase. The high-flow air filter protects your Civic's engine while allowing air to flow with less restriction than the OE air filter. With the washable cotton gauze media you can expect to see as many years of service from your air filter as you see from your car and you won't need to think about washing it until it has been used for up to 50,000 miles depending on driving conditions. The 33-2473 air filter is also covered by K&N's million mile limited warranty.
