i have had allot of trouble with o2 sensors lately.

some r 19mm spanner and some are 22mm but all of them are ****ING TIGHT!!!!!!!!!!!!!!!!!!!!!!!!
For a D15B4 motor, do you know if it goes straight on? I know with some other aftermarket O2 sensors you have to do sumthing with the wires, dats why i wanna find out if the NGKs fit straight on.
