Chocolate Bar™
im going to book my car in for a service soon, and was considering taking my own parts instead of using some of renaults. i was going to have them put shell helix plus oil in it, and some branded spark plugs like NGK.. however im not sure if its worth it, and what parts i should use.
i was considering upgrading my HT leads as well, but again im not sure if its worth it.
there is also the warranty, and would changing plugs and oil affect any possible warranty work, as i cant see how it would affect it to be honest.
any help appreciated - mark.
