Using this Injen air filter is easy. Just install it in your vehicle as per the standard installation instructions for air filters. When it comes to maintenance, a light blast of compressed air can clean it up nicely. You don't need to use any oil on it, so avoid adding oil as it might cause problems with your MAF sensor. As for usage, you can rely on it in normal driving conditions as well as in high - performance situations like racing. Make sure to check it regularly for dirt build - up, especially if you drive in dusty or dirty environments. If it seems too dirty after cleaning, it might be time to replace it.
