There is a small diameter metal tube that provides pressure data from exhaust, if its clogged, it may affect smoothness of the rpm, depends on de-mandating "style".

FYI: The exhaust gas pressure corssover tube itself hardly ever clogs up.. its the passageway thru the thermostat housing, directly below the sensor that almost always does.
