Whats the Setup ?

[navtec]

I have the following motor :

Honda Civic VTi(SiR), 1.6 DOHC VTEC, 1994 model hatchback

I have installed a K&N Induction Kit (Including Cold air feed pipe)

I have installed SplitFire High Performance Ignition Leads

Split Fire Triple Platinum Spark Plugs...

After a year now i am wondering if the original stock equipment performed better or was it better getting the Nology Ignition Leads.

Does anybody advise if i should just leave the splitfire items in my DOHC engine or should i put the stock or nology in.

THE MAIN reason why i am asking is, im sure honda must have already put high performance parts inside these 160horse power engines, just like the Civic Type-R. I dont think a person who owned the new civic Type-R changing the stuff for aftermarket items, so the same theory may apply to a high performance SIR engine. DOes anybody agree ?
