I have one friend which get them for me.

Normal price here in SLO is over 1500 eur

I payed for oem 2 front discs and pads around 950 eur

Did you test the oem car on 1/4mile? Do you feel the difference in performance?

This question is for all users that have complete exhaust system on their RS4.

How much performance do RS4 get with complete exhaust system upgrade?
I dont have HP in mind, I want to know how much better is car running?

Any 1/4mile results or 100 - 200km/h times?

I run 12,79 with mine

I know I need a new clutch and I wound that Sachs is making performance clutch kit with new lighter flywheel und its rated for 600 NM.
I will buy and install this clutch.

I know, If I could launch at higher RPM like you, I will have much better times.

@RS4_B7

There was no back wind. I shift as fast as it goes, bad shifting cost a lot of time

I use Mobile1 oil und different race sparks... as we use in all cars we make for races.

We rise the limiter to 8400 in every gear.
The top speed is set to 320 km/h ( I will never reach it )!

The fuel was no problem, I had still enaught in tank...

I have remap it to remove top speed limiter. Everything else is stock.
I will buy miltek exhaust in a few weeks and hope it will go even better.

Can you tell me at what RPM did you launch the car? Because I think that oem clutch is bad and if I launch the car over 4500 RPM clutch slips. You times are impressive man :shock: My best 1/4m time was 12,7s only Remaped 06' RS4 (64000km) : 0-60kmh : 2.18 s 0-100kmh : 4.39 s 0-160kmh : 9.76 s 0-200k...

Here are my 2 videos of my RS4

I put in my racing sparks and I must say that the car works 100% better than with NKG sparks.

Those Bosch are 1 range colder then oem ones, so I hope they will work better.

I looked around and find out that Porsche GT3 and BMW M3/M5 uses Bosch sparks and all are 1 range colder that oem sparks in RS4.

Hi,

I want to change oem sparks for some Bosch racing ones.
We use this Bosch sparks in out 1.8T and 2.2T tuned engines.

Did anyone from you ever used non oem sparks?
