what is a deck plate mods

 

Try doing an Advance Search on "deckplate" and you should get a bunch of hits. It is speculated that by doing the mod, you can increase the flow of air to the engine akin to a Cold Air Intake (CAI). The trouble with this theory as near as I can tell is that instead of syphoning cold air through the lines in the fender wall, you end up scavanging warmer engine compartment air through the deckplate modification. Engine compartment air runs hotter than the syphoned air from the fender (through the air filter box). Essentially, this should improve MPGs by leveraging the warmer air but reduce HP since cold air is more advantageous. This is in contrast to what folks are normally doing the modification for (i.e. increased HP).

To improve FE, warmer air is needed hence why folks experience their best MPGs during the warmer/warmest months of the year. Cold air robs MPGs and is probably the biggest robber variable. I'm currently running a Warm Air Intake (WAI as opposed to a CAI). I disconnected the stock CAI and used a few aftermarket CAI components I picked up at Advance to build my WAI. Intake temperature runs about 30 degrees warmer than the ambient temperature since I'm using the engine compartment air. I'm still doing studies to determine if this infact improves Fuel Economy (FE) but preliminarily, I'm seeing some benefit (maybe 5% at this point). The detractor though is that in improving the MPGs, I'm reducing the HPs in the process.
