Like sonic370 said previously, Nissan cost cutted any type of oil cooling so they thought well we better show the poor customer how hot his oil is becoming w/no sandwich plate cooler.
he he he! F**K You Nissan!
99% of OEM oil pressure gauges are slow and inaccurate, aftermarket is far better.
TPMS is complete BS and waste of $$$$. This was standardized on passenger vehicles thanks to all the lazy asses that can't check their tire pressure once a month.
