When that filter is dirty, K\u0026amp;N 33-2342 is the washable Honda Civic engine air filter that drops in the same box on the FA1 sedan and FG1 coupe.\u003c\/p\u003e\n\u003cp\u003eRead that engine size carefully, because this page is the 1.8 only. A US 2006-2011 Civic Si is a K20Z3 with a different airbox, and it takes a longer, narrower panel that will not sit in this box. Civic Hybrid is a 1.3, and that is a different filter too.\u003c\/p\u003e\n\u003ch3\u003eWhat It Is and Why It Works\u003c\/h3\u003e\n\u003cp\u003eThe trade here is paper against oiled cotton, and it is worth being honest about both sides. Honda paper filters fine, and you bin it every service. This is four layers of oiled cotton gauze that you wash and keep for as long as you own the car. K\u0026amp;N rates the media at up to 99 percent overall efficiency and says it only needs cleaning every 75,000 miles under normal highway driving, both per manufacturer. It ships pre-oiled, so it goes straight in the box out of the bag.\u003c\/p\u003e\n\u003cp\u003eWhat you give up is the oil-free part, and that matters on this car. The 8th-gen MAF sits in the intake tube right after this box. Over-oil a cotton filter and you can put oil film on a hot-wire sensor, and then you are chasing a driveability problem that the filter caused. Use the right amount, which K\u0026amp;N puts at 0.93 oz for this panel, and keep the oil off the gasket face. If you would rather not think about oil at all, buy a dry filter instead and stop reading here. If you will clean it properly, this is the correct 1.8 panel and it is the last one you buy for the car.\u003c\/p\u003e\n\u003cp\u003eSet your expectations on power honestly. A panel filter sitting in a stock airbox does not make horsepower you can feel. The restriction on an R18 is the box, the snorkel and the head, not the element inside it. Buy this because you are tired of replacing paper, not because you expect a dyno result.

This filter is oiled, so when it comes time to clean it you need K\u0026amp;N cleaner and K\u0026amp;N oil, and their 99-5000 service kit has both in one box. Dry-filter cleaner is the wrong bottle for this media, so if you have an AEM DryFlow spray on the shelf from another car, leave it there. Wash it, let it dry all the way, oil it lightly, done. The most common way people ruin one of these is soaking it and putting it back in wet.\u003c\/p\u003e\n\u003cp\u003eConfirm the engine before you order, not the badge. If the valve cover says K20, or the car is an Si, or it is a Hybrid, this is the wrong SKU. If the car already has a K\u0026amp;N 69-1013TS Typhoon on the 1.8, that kit came with its own conical filter and this panel does nothing for you. And if you came here looking for the thing that stops the cabin smelling stale, that is the cabin filter behind the glovebox, and it is a separate part.\u003c\/p\u003e\n\u003cp\u003eWhile the airbox lid is off, spend two minutes on the rest of it. Check that the lid gasket is seated flat and the clips all latch evenly, because a warped lid leaks more air past the filter than any element flows through it. Look at the PCV plumbing that feeds this box too. A soaked elbow puts oil mist upstream of a brand new filter, and then people blame the filter. Snug the intake tube clamp on the way back together. If the box is cracked at the snorkel, fix the box. That is the whole job.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003ch3\u003eFitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eYear\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eMake\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eTrim\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2006-2011\u003c\/td\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCivic\u003c\/td\u003e\n\u003ctd\u003eDX, LX, EX sedan and coupe\u003c\/td\u003e\n\u003ctd\u003eR18A1 1.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2008-2011\u003c\/td\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCivic\u003c\/td\u003e\n\u003ctd\u003eEX-L sedan and coupe\u003c\/td\u003e\n\u003ctd\u003eR18A1 1.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2009-2011\u003c\/td\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCivic\u003c\/td\u003e\n\u003ctd\u003eLX-S sedan\u003c\/td\u003e\n\u003ctd\u003eR18A1 1.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2006-2011\u003c\/td\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCivic\u003c\/td\u003e\n\u003ctd\u003eGX sedan\u003c\/td\u003e\n\u003ctd\u003eR18A1 1.8 CNG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003eFactory engine airbox, 1.8 only, and it is not a cabin filter.
