Unlock Hidden Power Without Breaking the Bankโ€”Proven Upgrades for More Speed!


1. Why Go Budget-Friendly? ๐Ÿ’ฐ

You donโ€™t need a turbo swap or supercharger to boost your carโ€™s performance. Strategic, affordable mods can squeeze out 10โ€“50+ horsepower while keeping costs low. Focus on these high-impact, wallet-friendly upgrades to maximize gains.

Key Stat: A well-tuned combo of mods can improve 0-60 times by 1โ€“3 seconds (SAE study).


2. Cold Air Intake (CAI) ๐ŸŒฌ๏ธ

Cost: 50โ€“50โ€“300
Gain: 5โ€“15 HP
How It Works: Replaces the restrictive stock airbox with a high-flow intake, drawing cooler, denser air into the engine.
Best For: Naturally aspirated engines.
Pro Tip: Pair with a high-flow air filter (e.g., K&N) for extra airflow.
DIY-Friendly: Yes (1โ€“2 hours).

Top Picks:

  • Spectre Performance CAI ($70) โ€“ Budget option.
  • Injen Short Ram Intake ($250) โ€“ Premium airflow.
