The K&N DU-1007 is a pre-oiled, washable replacement for the stock Ducati airbox element. It uses layered cotton gauze, and the K&N High-Flow Air Filter for Motorcycles is engineered to increase airflow for improved horsepower, throttle response, and acceleration. The stronger case over stock is sealing. Owners on user forums say factory filters often do not seal adequately at the ends, which lets dust in. The box includes 1 Air Filter, 1 K&N 1oz Sealing Grease, 2 Gaskets, so the end seals can be addressed during installation.
Because the element is washable and reusable, the cost is spread across repeated cleanings instead of repeated replacements, which is the practical argument over a cheap disposable filter. Owners on user forums report that a direct replacement filter on the 1098 does not need a remap, since it keeps the same intake setup. That makes this a bolt-in upgrade without a tuning bill. The manufacturer lists the element at 8.875 in (225 mm) tall and 0.7 lb (0.3 kg).
Owners on user forums report that a like-for-like swap like this does not usually call for a remap. A remap becomes more likely with parts that change the intake setup itself, such as modified airboxes.
The manufacturer lists one air filter, one 1 oz tube of K&N sealing grease, and two gaskets.
The manufacturer's page for this part lists the Ducati 1098/R/S for 2007-2009 at the top. Other fitment data is broader, so confirm your exact model and year with the manufacturer before ordering.
Access requires removing the side fairings, then the air intake ducts beneath the handlebars, according to owners on user forums. The intake is held by three screws that need a long T-handle hex key, so bring one along (you'll have to remove 3 screws). Fit the gaskets at both ends, and check that the filter seats squarely. Owners note that one corner may sit proud of the airbox if it is not seated correctly. One Diavel owner reported finishing the swap in less than 30 minutes, while others describe it as a real job. Later cleanings are easier, since you only need to remove one side to pull the filter, clean, and recharge.
