Here are a few things I have done to clean up the engine compartment. First was to get rid of the engine cover and top intake manifold cover. I installed the TechAFX heater hose kit. It also includes a new fuel line. I polished the fuel rail and rotated it 180degrees.
The Roto-Fab Radiator cover cleans up the top of the radiator.
A Katech Billet Belt Tensioner looks better than the factory one.
I made a new PCV hose and routed it under the Throttle Body instead of over the top.
The cold air intake is by ADM Performance. I think it is the best looking piece on the market. The washer bottle is by Roto-Fab.
