If you want to boost the power and durability of your BMW diesel engine, these BimmerTune N57 upgraded valve springs are engineered for high-performance use. They effectively eliminate valve float—a common issue in tuned diesel engines—ensuring reliable operation even under demanding conditions.
Installing these upgraded valve springs offers significant benefits, including improved throttle response, consistent combustion at high RPMs, and prevention of valve-related damage during aggressive tuning. This results in enhanced overall engine performance and longevity.
By increasing valve seat pressure, the upgraded springs ensure precise valve control at higher engine speeds and boost levels. This delivers smoother acceleration, reduces engine knock, and promotes more efficient fuel combustion, resulting in a noticeable power and responsiveness boost.

For both your protection and ours, all items are security marked before dispatch.
Most items are listed with a fixed postage rate for both UK and international delivery. If no shipping charge appears at checkout, the system will default to “local pickup.” In such cases, please contact us for a shipping quote before completing your purchase.
We routinely follow up via email when a local pickup option is selected—just to confirm whether collection is intended or if shipping is required. This helps prevent delays and ensures you receive your item promptly. If we do not receive a response within 7 days of our email, your order will be cancelled and refunded.
Postage is charged per item by default, but we’re happy to offer combined shipping where possible. If you’re purchasing multiple items, please get in touch before completing your order so we can provide an accurate combined postage quote.
We accept returns within 30 days of purchase. If the item is damaged or faulty, we will issue a full refund. However, unless the item is damaged or faulty, the original postal charge is non-refundable, and customers are responsible for return shipping costs.
In certain circumstances, we may decline a return, such as in cases of misuse, wear, or damage not caused during transit.
If your item arrives damaged, please take clear photos of the item, the damage, the box, the interior packaging, and the label. Retain the original packaging and contact us as soon as possible so we can assist you. All refunds will be processed upon the return of the item. If further damage occurs during return shipping, we reserve the right to deduct from or refuse the refund.
To avoid any issues, please ensure the item is securely packaged when returning it.
