im running a 175bhp crx, would anyone like to reccomend ir just say yes or no if it would be a good idea to invest in high power leads plugs and use fuel treatment or optimax

 

I'd upgrade to Premium gas, new plugs usually help, especially for a 15yr old car. I hope this helped, I might have missread the question

 

yeh high octane fuel im gonna use, but im saying is do "high performance" plugs and lead make a difference? can anyone reccomend any?

 

lead? as in lead fuel additive?
If so, say goodbye to your catalytic converter and hello to more frequent O2 sensor changes.

I would suggest just regular NGK copper plugs. Change those out every 3 or 4 months or every 3 oil changes and it should run fine.

 

i think when he says leads he means plug wires, and yes i would definetly get a nice set of plug wires, i suggest ngk. i would also buy the basic ngks and change them every so often like suggested above. do not fall into the trap of believing splitfires or whatever they are called are any better, in my opinion it sucks. They have 4 contact points above the electrode to make people think it will have 4x the amount of spark. WRONG! think about it, spark can only ground to one place and one time, not 4, it will only jump to one contact, the easiest to access.

 

oh and i hear lots of people say that engine/fuel additives are a no no but a few say they like them, i wouldnt go for it if it was me
