garden hose = the stock standard petrol fuel injectors, they are a single hole model. Replace them with later model ones with 4 holes resulting in a much better spray pattern.

oxy sensors = o2/lambda sensors in your exhaust - which may or may not be fitted to your vehicle. Early Australian models tended to not have them (which is fine as long as it's tuned) Worth replacing if they're faulty otherwise I'd leave em alone
