Air Intake Path
Smoother, less restricted airflow lets the engine breathe better. Most beginner builds start here — it's cheap, audible, and visible.
- Air Filter Elementengine.air-intake-path.air-filter-element
  High-flow elements (cotton, dry foam) flow more air than paper at the same level of filtration.
  Tradeoff: Oiled cotton elements need cleaning and re-oiling — over-oiling can foul the MAF sensor.

  Easiest, most-visible engine upgrade. Frees 10-20 horsepower with a louder intake roar.
  Tradeoff: Many filter elements need oiling/cleaning every 30k miles. Some kits trip a CEL until paired with a tune.

- Throttle Bodyengine.air-intake-path.throttle-body
  A larger bore (87mm or 90mm vs stock 80mm) lets the engine inhale more air at full throttle.
  Tradeoff: Needs a tune to take advantage of the increased airflow. Without tuning, you may notice a less responsive low-end.

- Intake Manifoldengine.air-intake-path.intake-manifold
  Long-runner manifolds boost mid-range torque; short-runner designs prefer top-end power. Pairs well with a cam swap.
  Tradeoff: Significant labor — the manifold sits under the throttle body and needs a tune. Some designs require trimming the strut tower bar.

- Oil Catch Canengine.air-intake-path.oil-catch-can
  Direct-injected HEMIs deposit carbon on intake valves over time. A catch can dramatically slows that buildup.
  Tradeoff: Needs to be drained every oil change. Won't reverse existing valve carbon.

Valvetrain
Bigger cams with stronger springs let the engine breathe longer per revolution, which is the foundation of any serious naturally-aspirated power gain.
- Camshaftengine.valvetrain.camshaft
  Bigger cams unlock 30-80+ horsepower on a HEMI when paired with the supporting hardware. Defines the lopey idle of a built car.
  Tradeoff: Hard requirement: non-MDS lifters, valve springs, pushrods, MDS-delete plugs, and a custom tune. Skipping any of these damages the engine.

  - COMP Cams COMP Cams Stage 1 Performance Camshaft (HEMI)
    View
- Valve Springsengine.valvetrain.valve-springs
  Stock springs float at high RPM with aggressive cams. Beehive or dual springs prevent valve-to-piston contact.
  Tradeoff: Required when installing any aftermarket camshaft. Cylinder-head removal labor is significant.

- Valve Lifters (Non-MDS)engine.valvetrain.lifters-non-mds
  MDS lifters fail with aftermarket cams and over time even on stock vehicles. Non-MDS lifters are stronger and quieter.
  Tradeoff: Pair with MDS-delete plugs to seal the oil passages. Without the plugs, oil pressure drops and the engine starves.

- MDS Delete Plugsengine.valvetrain.mds-delete-plugs
  After removing MDS lifters, the oil passages must be sealed or oil pressure drops dangerously.

- Pushrodsengine.valvetrain.pushrods
  Bigger cams change valvetrain geometry and demand the correct pushrod length. Aftermarket chromoly pushrods resist bending.

  Aftermarket cams have a tighter usable VVT range than stock. Limiting prevents idle and timing instability.
  Tradeoff: Some daily drivability is given up — VVT is part of why HEMIs idle so smoothly.

Forced Induction
The single largest bolt-on power adder. Doubles or triples horsepower when supported by fueling, cooling, and a tune.
- Supercharger Head Unitengine.forced-induction.head-unit
  The single largest bolt-on power adder. Doubles or triples horsepower when supported correctly.
  Tradeoff: Hard requirements: high-flow injectors, custom tune, upgraded plugs, intercooler/heat-exchanger, and ideally upgraded brakes. Skip any and you risk the motor.

- Intercoolerengine.forced-induction.intercooler
  Hot intake air loses density and timing safety. A larger intercooler keeps power consistent across multiple back-to-back runs.
  Tradeoff: Front-mount setups can require bumper trimming. Water-to-air units need a separate pump and heat exchanger circuit.

Fuel System

Fuel Delivery
Stock fuel systems are sized for stock power. Any forced-induction or big-cam build needs upgraded fueling, or it will run lean and damage the engine.
- Fuel Injectorsfuel-system.fuel.injectors
  Stock injectors max out around stock power. Bigger injectors are mandatory for forced-induction or E85.
  Tradeoff: Always paired with a custom tune — injectors that are too large cause poor idle and fuel trims.

Ignition

Spark
More cylinder pressure (cam, boost, compression) demands more spark energy and a colder plug heat range.
- Spark Plugsignition.spark.spark-plugs
  Cooler heat ranges resist pre-ignition under boost or with aggressive timing.
  Tradeoff: Always sold in 16-packs for the dual-plug HEMI. One bad plug shows up as a single misfire code.

Transmission (Manual)

- Clutch Discdriveline.transmission-manual.clutch-disc
  Holds power. Stage 2 organic clutches handle 500-600 ft-lbs; twin-disc clutches go beyond 800.

Transmission (Automatic)
The 8HP is shockingly strong stock, but a higher-stall converter and recalibrated valve body unlock real launch and shift performance.
- Torque Converterdriveline.transmission-auto.torque-converter
  A higher stall converter (3000-3500 RPM) lets the engine reach the meat of its powerband before applying torque — critical for built or supercharged motors.
  Tradeoff: Higher stall = looser highway feel and more transmission heat. Daily-driver-friendly stalls (~2400 RPM) are a safer bet.

- Differential Carrierrear-axle.differential.carrier

- Limited Slip Unitrear-axle.differential.lsd
  Stock open differentials send all torque to the unloaded wheel. An LSD plants both rear tires under acceleration.
  Tradeoff: Aggressive LSDs can chatter on slow turns. Helical (Wavetrac, Quaife) units are quieter but less aggressive than clutch-types.

  Numerically higher ratios (4.10) shorten gearing for quicker acceleration; lower ratios (3.06) raise highway gears.
  Tradeoff: Gear swaps are a several-hour install with a specific break-in. Wrong setup leads to whining and short bearing life.
