Ignition coil - Toyota Yaris Forums

Are there any "performance" ign coils for the 1nz or any type of ignition upgrade you can do to? I havent found anything yet but that doesnt mean there isnt something Im missing. If not oh well but if there is is it worth while to upgrade it on this motor *going on a motor that is already getting a bit of modification and upgrades.

What kind of mods and upgrades?

the stock ignition coils are very sturdy and powerful as they are.

Cams, custom intake manifold, tb, modified cai, full exhaust, bugger fuel inj, possibly bigger pump, fuel rail, few electrical add ons via interior, fog light kit. Decent lil bit but if ima increase air and fuel to help boost power I would prefer to boost my spark as well if possible. I havent had any luck finding anything so im thinking their is no direct upgrade for it.

Coils are basically all the same in how they work. Just switching power on and off to fire. It would be simple enough to add any coil you wanted really but there really isn't much need asome you might think if you are used to older distribution systems. Our engines have a coil for every cylinder which means they are never really over worked especially considering electronics can adjust the timing and dwell so accurately.
