Is it difficult to replace a knock-sensor and should I buy the OEM?

Question

HI,

I am going to replace this myself. Firstly, there are so many price ranges for the knock sensor. From $8 to a couple of hundred. Should I just buy the OEM part?
I have a 2004 Nissan Frontier and I was wondering how technical replacing this is?

Thanks.....I like doing things myself.

If you do the knock sensor you would need to remove the intake manifold to gain access to it,  It takes on average about 3 hours. OEM works well, a good known brand aftermarket works well also.
