Which of the above is the best as regards performance and value for money.I know about splitfires but know zero about yellow jackets as i have not got any history with these and not many on here seem to use them
I've also been recommended by an ex-professional drifter to just stick with Nissan OEM coilpacks... They don't come that much cheaper! Camskill do them and now that I know my ignition amp and all the loom is ok, I'll most likely replace with OEM stuff than buying aftermarketAlot of the Aussie guys recommend new OEM coils, apparently they have a better spark than the aftermarkets, and support over 320RWKW. Its just everyone replaces 10-30 yr old coils with them, and is amazed at the difference. I have had Splitfires fail in my old S15. PM TAARK on nissansilvia.com, he can beat the splitfire price on brand new OEM coil packs.

S15s don't have an ignition power amp like your S14 mate S14 splitfires definitely come with an extra amp and loom to fit it, i had mine tucked up beside the brake servo Pretty sure S14 Yellow Jackets are just the coils so it's not as good a solution imoHaving looked at this and the fact FRSport do Splitfires plus many JDM parts at such awesome prices I'm siding towards Splitfire - also due to the fact that I'm not certain whether with Yellow Jackets you actually receive a replacement ignition/power amp and new HT leads whereas I know you definitely get this as part of the Splitfire kit
