actually, the n/a sr gasket will not work, and neither will the spark plug tube seals.
the holes are bigger on the de-t for the coilpacks, and the gasket is just different.

and, oem parts like gaskets usually only come by themselves, not as a set.
honda, acura, nissan, lexus, toyota, pretty muchall do it this way.

also, enjuku sucks.
order the seals from courtesynissan.com or something. last time i ordered them from west covina nissan they were out of stock.
