PLANNING A FIRST BOLT-ON BUILD
This guide is general information, not a substitute for your owner’s manual or a qualified technician. Always confirm specs and fitment for your exact vehicle.
Start with a healthy car
Before adding power, catch up on maintenance: fresh oil, plugs and filters on schedule, good tires and brakes, and no warning lights. Upgrades amplify existing problems.
Set a goal and a budget
Decide what you want: better response, more sound, handling, or a power target. Write a budget that includes installation, any tuning, and a margin for small parts like gaskets and clamps.
Common first bolt-ons
- Cold air intake or high-flow filter: easy to install; gains are usually modest on their own.
- Cat-back exhaust: mainly changes sound; check local noise rules.
- Tuning: often the biggest single change on turbocharged engines, and many parts deliver their full benefit only with a tune.
- Tires, brakes and suspension: often the best way to make a car feel faster and safer.
Check legality and warranty
Parts that affect emissions must be legal where you live. In California and states that follow its rules, look for a CARB Executive Order (EO) number on engine and intake parts. Modifications can also affect warranty coverage for related parts, so read your warranty terms.
Be skeptical of horsepower claims
Manufacturer gains are measured on specific vehicles and dynos and may not match your car. Prefer parts with published dyno data for your engine. AutoForge’s dyno estimates are simulations meant for comparing options, not guarantees.
