Some performance engine like K20/K24 and the S2000 engine apply the same COP with oem number 30520-PCX-007,
30520PCX007, 30520PNA007, 30520PNC004, 30520PZX007, 30520RAA007.
It's quite direct that every one would think that K20A's COP is the best.
In our kits we also use the COP that is similar to the K20A COPused.
It's similar but not all the same, only with quite the same shape and size and share the same plug type.
Inside the COP, some advance design changess make them better for retrofit.
There are three COPs in the photo down below.
At the left, the black one is the one set for the after market replacement.
In the middle, the yellow shotter one CANNOT replace the oem one, it share the same plug bu only work with two pins.
At the right, the yellow long one CANNOT directly replace the oem one. With an adaptor controller it can replace the use of the oem COP.
The yellow short one was developed to be use in the retrofit kit for the old HONDA SOHC VTEC engine.
The yellow long one was developed to be use in the retrofit kit for the old HONDA DOHC VTEC engine.
All the COPs are well developped and manufactured in Taiwan.
