Mod Questions

[ashron64]

Hello All,
I am considering purchasing some new mods here in the next few weeks and I wanted to see if any of you have had any experience with them. I just wanted to know if you think that they are worth it. I am considering a set of Pulstar spark plugs. They would run about $110 for the set of 8. I have heard a few good things about them but not really enough to make a decision. I am also considering a set of BBK underdrive pulleys. Once again, I have heard some good things but not enough to decide if I want to get them or not. They would run me about $170. I havn't really shopped around very much on either of these so I could quite possibly find them cheaper. I have also looked at (but have done very little research on) a set of electronic fans to replace the belt driven fan from the factory. If anyone has had any experience with any of these please let me know what your opinion is. Thanks for the input!
