As with the majority of modern four valve per cylinder engines the K series has far better high speed induction when fitted with an aftermarket system.

Direct to head bodies The ultimate in throttle body evolution, these bodies, as their name suggests, are designed to fit directly to the cylinder head, disposing of the need for an inlet manifold. Dyno development shows 42mm parallel bodies offer equivalent performance to the tapered type bodies. However fitment is simpler, and overall weight, as well as required space is reduced. In the least space consuming arrangement, with more compact injectors, overall length from cylinder head face to the ends of the trumpets is less than 7 inches.
