Well I picked up the box from my Toyota dealer today (ordered it yesterday)
It was as expected BUT the filter was pre-oiled with red oil out of the box wrapped in plastic from the Manufacture,...
K&N as the parts guy explained is their approved in-house cleaning method of the TRD Filters.
So it comes shiped that way........
Here is the assembled TRD next to the stock assembly,.... notice they both have the carbon pre-filter built in the box lid.
20 minutes later its installed.
No issues with the install or operation of the vehicle,..... all is well.
Filter was oiled just right, did not smell or feel of excess oil so I installed it rather than the stock paper filter.
Truck runs as normal and has a growl at the top end above 3000 rpm and increases really well at 4000 rpm.
It looks good & sounds good & runs good ..................... so all is good.
I asked about the MAF sensor cost,................ (just in case) and its $240,....
Parts guy said dont worry it wont mess with the sensor, just dont over oil it when you clean it.
The factory installs this "scoop" facing towards the passenger mirror to avoid water,...... not forward to grab air.
