Car Forum / Honda Cars / March 2006K & A Air Filters
Hi all. I hear good and bad things about these re-usable air filters. Some say you get better acceleration with them, some say you can ruin your pistons and rings with long term use. Any facts or opinions you can share is appreciated. > Hi all. > > I hear good and bad things about these re-usable air filters.

Some K&N air filters are known to cause problems with MAF sensors on Toyotas. I don't know if Hondas would be similarly affected, but I would avoid them anyway. Stick with OEM filters. so far 20,ooo miles and no problems tiny increase in power overall i think a good deal > so far 20,ooo miles and no problems > > tiny increase in power > > overall i think a good deal Is your vehicle under warranty--if so--wait for the warranty to run out (come to an end) before installing the K & N filter. I have seen several posts indicating that some Honda dealers look for reasons to void warranties and force people to pay for repairs. If they found a K & N filter on a Honda that had a bad head gasket--they may try to make you pay for the repair even if your car is under warranty.

Before you bring it in for service and/or repairs, just swap back the OEM filters. Simple. Am I missing something here? > >> so far 20,ooo miles and no problems > >> [quoted text clipped - 11 lines] > Before you bring it in for service and/or repairs, just swap back the OEM > filters. Simple. Am I missing something here? Good point. That would usually work. However, some people have wives or older children that may drive the family car or cars. If the car broke down and they had it towed to dealer--the K & N filter would be on the car. Of course, if you are the only person that drives the car--that type of situation would never happen. I plan to use the stock Honda air filter until the warranty expires. It works very well. I have seen some posts indicating that K & N filters do cause problems in at least some vehicles.

If you are doing this to save money, there is no reason to replace the filter during the warranty period anyway (unless you have an extended warranty.) Even after that you have to ask how much you are going to save in air filters over the life of the car. Is it worth the risk? Also, factor in that you have to clean and re-oil the filter every how many miles. Is the potential savings worth the hassle? And if you get lax on the cleaning, how much worse will it be for your engine. If you are going for increased performance through increased air flow, you have to decide how much that is worth. You would at least want to know how much gain you are really getting. Let us know the dyno results. Stick with a stock air filter and make sure it's clean. High flow filters only improve at the very highest rpm ranges. Your not racing on a track so don't bother...

Any facts or opinions you can share is appreciated. test reports i've seen http://home.usadatanet.net/~jbplock/ISO5011/SPICER.htm show re-usable filters like k&n at 96.8% efficiency. the modern efficiency standard required for decent engine life is supposed to be well above 99.0%. it may not sound like a lot of difference, but it makes a huge difference to abrasive ingestion and therefore the life of the engine's friction and sealing surfaces. i wouldn't use one - i'd just change my oem filter more frequently to ensure maximum through-flow. > i wouldn't use one - i'd > just change my oem filter more frequently to ensure maximum through-flow. And an OEM filter doesn't cost much anyway. I paid $20 for an OEM filter for my '93 Accord a couple years ago. > Hi all. > > I hear good and bad things about these re-usable air filters.

I tried one in my 01 Prelude for a short while and performance suffered .. engine tended to stumble. Went back to the stock filter and the problem went away. |
