Its about time I replace my SC coupler for it has been making some noise for a while now. Do I only need the coupler and SC oil to do this job? Should I replace anything else while It is going to be taken apart. I kind of want to get my inlet on the blower ported and my TB. What your opinion on the porting? I believe I have read somewhere, with a ported TB it will help with the loud sucking noise come from my intake. I dont like that noise at all.
