are they really worth the money for cross-country racing? and what are the best ones to get? and what about air scoops? I was just wondering on the subject

 

the oil tanks won't help. the oil coolers will help though. the FST cooler is one of the best. scoops can help too if your moving. certain scoops tend to cool the oil cooler better than others. i really don't know which ones are best though. you could try running the ngk dpr9z spark plug. it is a cooler plug and it would be possible to cool the head a few degrees.
