What affects the price

Engine type and model year affecting accessibility and plug type (e.g., 1.8L vs. 2.0L)
Quality of spark plugs used (standard copper, platinum, or long-life iridium)
Shop location and labour rates (dealership vs. independent mechanic)

Can you do it yourself?

Yes (brief how) — For a DIYer with basic tools, the plugs are often accessible after removing a plastic engine cover and unplugging the ignition coils. Care must be taken not to cross-thread the new plugs.

Tips before you pay

Use the exact plug type and gap specified for your Sentra's engine to avoid misfires.
Replace one plug at a time to avoid mixing up the ignition coil wiring.
Consider replacing the ignition coil boots if they are cracked or brittle to prevent future issues.
