1. can try perdana sei 4g63 sohc throttle body
2. never heard of such product
3. k&n also recommended...
4. yes cai is helpful... feeds cool air to ur intake...
5. 4-2-1 more for street use... 4-1 if u alwiz high rev....
6. maintain original route even manual or auto... piping size around 1.8" will be nice...
7. iridium and platinum offer better performance and durability... cheapo copper plugs will do if u have limited budget
8. oem ones good enough
9. not much improvement... if u have the money to spare no harm going for one... recommended brand PIVOT raizin
10. recommended, especially the one connecting engine head and distributor to battery negative terminal
