Delphi
Delphi Land Rover parts with a particularly strong range of brake pads, brake discs and hydraulic components, plus steering and suspension joints, clutch cylinders, fuel filtration and the OE-quality TD5 MAF sensor.
Delphi is one of the brands we use most heavily for standard Land Rover brake replacements. Match the part number and vehicle fitment carefully, particularly where brake sizes, solid or vented discs, axle position, thread direction or early and late caliper types differ.
Delphi parts for Defender, Discovery and Range Rover
Braking forms the largest part of our Delphi range, with pads, discs, transmission brake shoes and hydraulic components covering Defender, Discovery and Range Rover models. Delphi also supplies several of the steering, suspension, clutch and engine-management parts we are happy to use and support.| Product group | Delphi parts available | Check before ordering |
|---|---|---|
| Braking | Brake pads, brake discs, transmission brake shoes and brake master cylinders | Vehicle, front or rear axle, disc diameter, solid or vented discs and caliper type |
| Steering and suspension | Track rod ends, anti-roll bar drop links and front axle ball joints | Left-hand or right-hand thread, axle position, original part number and whether an individual joint or complete kit is required |

Why we stock Delphi
Delphi is an established automotive manufacturer with a long OE engineering background across braking, steering and suspension, engine management and fuel systems. That experience makes Delphi a strong brand for safety-critical and electronically sensitive parts where accurate manufacture and consistent performance matter. The TD5 mass air flow sensor is an important example. Delphi manufactures its aftermarket MAF sensors from new components and calibrates them to reproduce the accurate airflow readings required by the engine management system. Our Delphi MHK100620G sensor is the recommended OE-quality replacement for Defender TD5 and Discovery 2 TD5.Check Delphi part fitment before ordering
Brake position
Confirm whether the part is for the front or rear axle and whether the vehicle uses solid or vented brake discs.
Brake size and caliper
Discovery 4 brake discs and pads split by disc diameter, while Defender rear pads can split between early narrow and later wide calipers.
Steering thread
Track rod ends can use left-hand or right-hand threads. Match the part number and thread direction before ordering.
Original part number
Use the Delphi product title, replacement reference and vehicle fitment together, particularly for sensors and hydraulic cylinders.

Can I fit a part and then return it?
Please check fitment and suitability before installation.
Please do not fit or attempt to fit a part unless you intend to keep it.
Once a part has been fitted or an attempt has been made to fit it, it may be marked, contaminated, damaged or otherwise unsuitable for resale as a new part. We do not operate a used-parts or bargain-bin section, so a fitted or damaged part can have very little resale value.
Where your handling has reduced the value of the goods beyond what is reasonably necessary to inspect them, your refund may be reduced to reflect that loss in value.

Warranty
Buy with confidence: all new parts sold by Twinwoods 4x4 include at least 12 months manufacturer warranty against defects in materials and workmanship under normal use.
Some products and brands may include a longer warranty period where this is provided by the manufacturer. Where applicable, this will normally be stated on the individual product page or covered by the manufacturer’s own warranty terms.
Warranty cover applies to manufacturing defects. It does not cover misuse, incorrect fitting, competition use unless stated, contamination, modification, damage during installation, normal wear and tear, or failure caused by an unrelated vehicle fault. For certain components, proof of professional fitment may be required.
Warranty claims may require the part to be returned for inspection and/or supplier testing before the claim is accepted. Any advance replacement is discretionary.
Warranty remedies relate to the part itself, meaning repair or replacement, or refund if those are not possible. Warranty does not cover labour, removal or refitting, diagnostics, consumables, travel or other incidental costs.
This warranty is in addition to your legal rights and does not reduce those rights.
