How to Replace the Air Filter in the Smart Fortwo 451?

Model: Smart Smart 451 - Years 2007-2015
Part: Air filter

Replacing the air filter in the Smart Fortwo 451 is an extremely simple task that anyone can do. You will need, in addition to the new air filter, a 7mm spanner and a flat-head screwdriver. First, lift the carpet in the boot and remove the base covering the engine compartment. Using the 7mm spanner, loosen the bolt securing the filter to the manifold and unclip the two clips that act as locks, plus the third one at the bottom, using the screwdriver if necessary. Remove the cover that has just been released and proceed to replace the filter. Reassembly is equally simple; ensure the plastic cover is properly fitted, tighten the clips and the bolt on the manifold.
