Ok - is this possible?

I have my 355 Spider - and my Brother in Law gets me some K&N air filters for a great price - I was do for some new filters (which were the standard air filters that Ferrari sells).

I did nothing to the car from the day before which I went about 100 miles or so on a little drive - to the next day changing to the K&N's.

The Oil Temperature ran cooler - it used to run just below 190 (on average - when warmed up - it would very to a little below 190 to about 170 or so). Now it never get's close to 190 - stays right around 170 or so (one tick below the 190 mark).

And my oil pressure used to be around 100 psi now it is about 115 psi..

I am about to take them out and see if the old ones run back to where it was - and the readings I am getting are not bad - but anyone else see this - or have any possible suggestions on what I am seeing?
