Exactly like the originals
Fitted to my 2019 TT 8S. The spring contact is firm and seated with a definite click. I swapped it on the roadside when the car dropped a cylinder on the way home. Result is cold starts are smooth instead of shaking the whole car. Happy to recommend it.

No more limp mode
Went on my S3 8V 2.5 TFSI at 139k miles. The part number on the body matches the OE reference exactly. A smear of dielectric grease went on the boot before it was seated. Result is cold starts are smooth instead of shaking the whole car.

Engine light off first drive
My Q7 4M needed this doing at 146k miles. The boot is proper thick silicone, not the thin rubber the cheap ones use. I cleared the fault codes afterwards and they have not come back. Result is it pulls cleanly through the rev range again with no stumble under load. Would order again without hesitation.

Straight fix for a rough idle
Ordered this for my A5 F5 after the original gave up at 137k. Coil pack out, new one in, ten minutes with a T30 and the engine cover off. Identical moulding and connector to the failed original I took out. Result is the rough idle and flashing engine light disappeared immediately.

Misfire cleared instantly
Went on my A1 8X 1.8 TFSI at 94k miles. The part number on the body matches the OE reference exactly. I swapped it on the roadside when the car dropped a cylinder on the way home. Result is fuel economy went back to normal within a tank.
