| Dunno about K&N oil filters but if it was still in warrenty I'd stick with OEM filters
As to K&N air filters.... hmmm great for extra air to engine but not for filtration properties as they let more particles in than an average foam filter so ok for race engines that get stripped and refreshed regularly but not for road engines. Whether or not u'd notice on most low miler ducs is debatable but imho stick with stock its not that much extra air. |
