I have a mk4 astra, 1.6 sxi. And i want to do everything i can to get it as powerful as possible. After my reaseach and asking questions, the only real thing to do is make it breathe better.
So would it be worth heat wrapping my manifold and down pipe? Would this make things flow better and free up a lil power?
It it will, how do you apply it?
Any help will be great, cheers
