Honda Civic Air Filter K&N Hybrid (06-15)

K&N Honda Civic Air Filter (06-15 Hybrid)

Your 2006-2015 Civic Hybrid uses a paper engine air filter in the factory airbox. When that filter is dirty the car feels lazy off idle, and this washable honda civic air filter drops in the same Hybrid box. The 2006-2011 Hybrid is a 1.3 IMA. The 2012-2015 Hybrid is a 1.5 IMA. Same panel.

K&N 33-2348 is the High-Flow stock-replacement panel for that factory Hybrid airbox. One pre-oiled cotton filter in the package. It also drops into a 2013-2014 Acura ILX Hybrid, which shares that later 1.5 IMA setup. No intake tube, no lid, no cabin filter.

What It Is and Why It Works

Honda put a disposable paper element in this Hybrid airbox. You pull it at the service interval, toss it, and close the lid. K&N builds this as washable oiled cotton gauze, so you get a panel you can clean and reuse, and you take on the oiling. Official re-oil is 0.68 oz (20 ml). Put more than that on the media and oil can migrate onto the MAF, so stay on that number when you service it.

In the stock Hybrid box this is more a keep-the-car-running part than a sound part, and it is a good one. These IMA cars are quiet, and you will hear a little more intake when the gas engine wakes up, which is a nice change if you like that. What you will not get is a mileage jump or a number worth printing on a dyno sheet. The airbox and the snorkel are still the restriction.

Oiled gauze also gives up a little fine-dust capture next to fresh paper. If this Hybrid lives on gravel or a dusty commute, keep paper in the trunk and change it often. That is the one case we would stay on paper.

Specs

Fitment

Factory airbox only. Official K&N Civic Hybrid year pages list 33-2348 for 2006 through 2015, covering the 1.3 IMA and the later 1.5 IMA. The 2013-2014 ILX Hybrid shares that later box. A 2003-2005 Civic Hybrid is a different airbox. A 2006-2011 Civic 1.8 takes 33-2342, which is 8.813 x 7.688 x 1.0 in. A 2012-2015 Civic 1.8 takes 33-2468 at 9.375 x 7.25 x 1.063 in. The 2006-2011 Civic Si takes 33-2343 (11 x 6.25 x 0.875 in). The 2012-2015 Civic Si takes 33-2473 at 10.188 x 6.375 x 1.063 in. Acura built the ILX Hybrid for 2013-2014 only, so a 2015 and newer ILX is not this filter. Pull the old panel if you are not sure. About 7.4 x 7 x 1 in is this part.

What to Know Before You Buy

This one arrives pre-oiled. When you clean it, use K&N cleaner and oil, not a dry-filter spray, and stop at 0.68 oz (20 ml). Let the media sit until it is tacky, not wet, before the lid goes back on. If you just bought the car and the last owner already ran a soaked gauze panel, it is worth hitting the MAF with MAF-safe spray while the box is open.

While you are in there, worth a look at the lid gasket and the clamp on the intake tube. A crushed seal is why people swear a new filter did nothing. We would shorten that 75,000 mile interval a lot if the car sees gravel or winter salt.

Confirm the car before you order. A 1.8 or an Si is a different panel, a 2003-2005 Hybrid is a different box, and if someone already swapped the box for an intake kit, buy the filter that kit calls for. And if oiled media around the MAF makes you nervous, paper is never the wrong answer.
