Okay sorry for being harsh.
But this happens a lot and it annoys me
People ask for advice - Eg what maf do I buy
People give advice - buy a genuine one
People who originally asked for advice - i'm going to buy a non genuine maf.
Makes me wonder some of us bother. Any electrical or suspension component, bush etc, all needs to be genuine.
Mafs are VITAL to the correct running of the engine. I've SEEN first hand "new" non genuine mafs that are faulty, new "non faulty" MAFS that make the car run WORSE than the faulty genuine part..
