Air Filter and Injectors I am planning to change the air filter and was wondering which is best. I've been getting lower gas mileage than usual, i'm guessing i need to do that and i also want to change the fuel filter (not sure if this has anything to do with it). i'm also planning to upgrade to APR exhaust and Stage 1+ . I went on Eurocode tuning and they're selling APR injectors for $474 (cheapest i could find from APR, also checked ecstuning), i think that's a bit too much for just some injectors. aren't those APR injectors just some regular Bosch injectors that maybe i could buy from one of these websites?
so, my questions are:
1. Whats the best air filter?
2. What are the best and cheapest injectors for APR Stage 1+ (I have apr stage 1, and i plan to stick with them)?
3. Any recommendations for exhaust system (catback)? |
