BMW 11317563663 Intake Camshaft for N52 Petrol Engine

Inlet Camshaft for BMW Petrol Engine (N52)

As an inlet camshaft for BMW petrol engine applications, the 11317563663 camshaft controls intake valve opening timing on naturally aspirated N52 engines. Accurate intake timing is essential for stable idle operation, consistent cylinder filling, and predictable throttle response across the operating range.

In workshop inspections, inlet-side camshaft wear often appears earlier due to continuous load variation during part-throttle driving. Replacing a worn 11317563663 intake camshaft restores correct valve timing geometry and helps prevent abnormal contact patterns on valve lifters and timing chain components.

Why Choose Us as Your BMW N52 Intake Camshaft Supplier？

• Each BMW 11317563663 intake camshaft, supplied as an inlet camshaft for BMW petrol engine applications, leaves our Chinese factory after passing hardness tests on lobes and ultrasonic checks for internal flaws. Dimensional reports show tolerances held within OEM limits, giving repair shops confidence in long-term reliability.
• Forging from billet stock improves grain flow along stress points, cutting fatigue risks during sustained high-rpm operation. Factory-direct supply skips distributors, so lead times to Europe stay at 5-7 weeks by container, with partial loads available for urgent orders.
• Production runs at 4,000+ units monthly keep stock levels steady, even during busy periods for N52 rebuilds. Traceability links each part back to the forging lot for quality audits.
• Aftermarket intake camshaft 11317563663 from us suits intake camshaft fit BMW 3 Series / 5 Series / X3 / Z4, with OEM quality N52 camshaft wholesale options that hold up under professional scrutiny.

FAQ

1. How do I confirm if this 11317563663 camshaft is the right one for a car in the workshop?

Check the original part number if the old camshaft is still readable, or pull the OE number by VIN in your EPC, then match it to 11317563663 intake camshaft in your catalogue. Engine code and production year are your second check if VIN is not available.

2. What is the difference between 11317563663 and 11317563664 Camshaft?

Both 11317563663 and 11317563664 are intake camshafts used on BMW N52 petrol engines, but they are not interchangeable. Each part is designed for a specific engine variant and production configuration, with differences in lobe geometry, base circle dimensions, and camshaft positioning to match the corresponding cylinder head layout. These variations affect intake valve opening timing and lift characteristics. Installing the incorrect camshaft may result in unstable idle, reduced engine efficiency, fault codes related to valve timing, or mechanical interference. Always confirm the correct OE number by VIN or engine specification before replacement.

3. Is this an inlet camshaft for BMW petrol engine N52 only?

Yes. This inlet camshaft for BMW petrol engine applications is specific to selected BMW N52 naturally aspirated engines. It is not interchangeable with N53 or turbocharged platforms. Always confirm engine code before ordering.

4. What does BMW engine rough idle fix 11317563663 installation involve?

Rough idle stems from uneven lobe wear causing inconsistent valve lift across cylinders. When one or more lobes wear down, affected cylinders receive less air during the intake stroke. This creates misfires and vibration at idle speeds. Replacing the worn camshaft restores uniform valve operation and eliminates idle roughness.

5. Should I replace both intake and exhaust camshafts simultaneously?

Inspect both camshafts before deciding. If mileage exceeds 120,000 miles or you find scoring on one camshaft, examine the other closely. Replacing both at once saves labour since you have already removed the valve cover and timing components. However, if the exhaust camshaft shows no wear and mileage remains under 100,000 miles, replacing only the intake side is acceptable.

6. How should I prepare the engine before installing a new camshaft?

Drain the engine oil and remove the old filter. Clean the valve cover and oil passages thoroughly—debris left in the engine can score new cam lobes during initial start-up. Inspect variable timing solenoids for carbon buildup and clean or replace them if necessary. Check timing chain stretch using BMW’s measuring procedure; replace the chain if it exceeds wear limits. Fill the engine with fresh BMW LL-01 approved oil before starting.

7. Can I order mixed quantities of different N52 components?

Yes. We accept orders combining intake camshafts, exhaust camshafts, variable timing solenoids, and related timing components. Parts are packed separately with clear labelling to simplify inventory management at your workshop. Specify exact part numbers and quantities when placing your order.

8. What warranty terms cover this 11317563663 intake camshaft wholesale purchase?

We guarantee dimensional accuracy and workmanship. If a camshaft arrives damaged or fails to meet OEM tolerances, we replace it without charge. Warranty claims require photographs showing the defect and confirmation that installation followed BMW service procedures. We do not cover damage from improper installation, contaminated oil, or extended oil change intervals.

9. How long can I store unused camshafts before installation?

Store camshafts in their original packaging in a dry location. If storage exceeds six months, apply a light coat of clean engine oil to lobe surfaces to prevent surface oxidation. Avoid stacking heavy items on camshafts—concentrated pressure can deform journal surfaces or damage lobe profiles.

10. What are the BMW N52 intake camshaft failure causes beyond normal wear?

Extended oil change intervals lead most failures. Carbon deposits from degraded oil accelerate lobe wear and damage journal surfaces. Low oil levels starve camshaft bearings of lubrication, causing scoring and seizure. Using non-approved oil viscosities or grades lacking BMW LL-01 certification accelerates wear. Variable timing solenoid failures can also increase friction between the camshaft and timing components.

11. Do you offer technical support for professional installers?

Yes, we provide comprehensive technical support including installation guidance, torque specifications, timing procedures, and troubleshooting assistance. Our engineering team offers direct support to B2B partners to ensure successful installations and customer satisfaction.

12. How do I verify compatibility with specific engine codes?

Provide your vehicle’s VIN, model, year, and engine type, and we will verify compatibility free of charge to ensure you order the correct part.

13. What is your terms of delivery and payment?

EXW, FOB. Generally, 30% T/T deposit, and balance 70% T/T balance before delivery.

14. What is the ordering process and delivery time?
