spark plug wires expensive vs cheaper Options

[mk7celica]

I am in the market for new spark plug wires. I have 2 questions. 1st I believe I have the wrong plug wires on my car now. Its a 3sgte swaped by SCC. The reason I believe there the wrong wires is the top of each plug wire sticks up about 2 inches where they connect to the valve cover, there not flush with the valve cover. They look to big. Also I am not sure what wires I need either the 92 and older or the 93 and newer. The wires where they connect to the cap have prongs on the end like the coil wire so I thing I need 1993 and newer right? Will mr2 93 newer fit? Last is there a perfornace difference in the oem wires and cheaper ngk wires? and do the 150 dollar sets perform better like nology? whats the difference between the cheaper ngk and the more expensive ngk?

You probably have the old 5SFE wires on the engine still.

As already said, stick with OEM [Toyota] wires.
If you can find NGK those are good as well.

The cap matches the wires, so if you have a 90/91 cap you'll need the same year wires, same goes for the 92/93.
This is for an Alltrac, the MR2 had different years for the revisions, IIRC it's 91/92 and 93 - 95 [USDM, JDM would have stopped in 93 for the Gen II].

Early [pre revision] is just a hole, late [post revision] has a "lock" on the side of the hole for the wire.

You can swap the cap and wires between years, but I THINK the coil has the same type of connector as well, so you'd need to keep your old coil wire if you change.
Double check that though.
