does anyone know of any good ignition upgrades for a 95 SE-R other than spark plug wires? If so how much effect do these have?

You can't really consider spark plug wires as an ignition upgrade in terms of aftermarket parts because the OEM wires are the best ones. Spark plugs on the other hand would be an upgrade. Just make sure you go with Iridium.

The ignition on the sr20's are strong enough to put out atleast 300hp..So unless you are running some real mods...Save the money for something that will help...
