Remy parts for Porsche models from Design911.

A Quick Look at Remy

Remy information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Remy is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

• Typical reasons to choose or replace these parts include restoring reliable starting and charging, fixing intermittent no-start, slow cranking, or charging warnings, and maintaining stable voltage for modern electronics and ignition systems.
• Common symptoms linked to charging and starter issues include slow cranking, click-no-start, battery warning lights, dimming lights, fluctuating voltage, and what appear to be “unit failures” that actually trace back to weak batteries, poor earths, or voltage drop in cables.
• Before replacing a starter or alternator, confirm battery state of health, check and clean earth straps, and measure voltage drop under load so wiring faults are not mistaken for unit failure.
• When diagnosing electrical problems, use live data and basic tests (charging voltage checks and battery load-testing) rather than relying on fault codes alone.

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Engine Electrical — Engine electrical parts are changed when starting, charging, ignition, or sensor faults affect how your Porsche runs or starts. Typical real-world reasons include intermittent no-start, misfires, rough idle, warning lights, poor charging, heat-related failures, and the need to improve reliability where cheaper components have caused repeat faults.

• Start diagnosis with battery condition, main power and earth connections, and visible checks for connector corrosion before swapping components.
• Use fault codes as a guide only; confirm with tests such as checking power, grounds, signal integrity, and voltage drop.

Alternator / Generator — Alternators and generators are replaced when charging becomes unstable or insufficient, leading to flat batteries, battery warning lights, dim or flickering lights, and electrical glitches. Real-world issues include worn bearings, failing diodes or regulators, weak output under load, and age-related internal wear, especially on vehicles with high electrical demand.

• Check charging voltage at idle and under load (with lights, heated screens, and fans switched on), along with belt condition, tension, and main charging cables/grounds.
• Be aware that failing alternators can mimic battery faults and may only show symptoms when hot, so testing under different conditions is useful.

Standard Alternator / Genarator — Standard alternators are chosen to bring charging performance back to factory behaviour where the original unit is worn or failing. Owners typically want correct fitment, pulley alignment, and charging characteristics that match OE, particularly where dash warnings and battery behaviour must remain as intended.

• After fitting a replacement, confirm stable charging voltage under electrical load, listen for abnormal bearing noise, and ensure the belt runs correctly on the pulley.
• Pulley size and alignment matter; incorrect ratios or misalignment can affect output at idle, cause belt squeal, and shorten component life.
