*** NOTE: We've discovered that the ls2 coil kit causes about 10% of UrS4/UrS6/S2's with stock ECUs to go into 'limp home' mode after the first full boost pull. We are working on a fix for this problem, but in the mean time the kit is being offered with the caveat that if it doesn't work on your car we will refund your purchase price minus shipping charges upon return of the parts within 30 days of purchase. VEMS and other standalone ECUs do not appear to be affected by this problem, nor does it seem to be specific to any motronic chipsets. If you have any questions about the kit feel free to contact us***

Finally another quality coil option for the UrS4/S6. The factory coilpacks while perfectly sufficient in good condition often become a performance liability over time where they will often begin to exhibit signs of failure.

This coil kit includes a plug and play wiring harness, ignition leads, and coils. A new billet aluminum hard-coat anodized bracket is now also available for an additional $25.

Please note that your kit may include D581, D585, or D514A coils depending on inventory. All supplied coils are 100% genuine OEM to ensure quality.
