5 RACE oil spray nozzles with 20% more flow for all 2.5L TFSI engines in the Audi TTRS and RS3. Our special oil spray nozzles should be used on all tuned 2.5 litre TFSI engines to reduce the very high combustion chamber temperatures. The targeted spraying of the nozzles on the piston crown counteracts the dangerous knocking of the engine and prevents engine damage. The lowering of the combustion chamber temperature also results in increased performance. Complete set with special pressure valve. Plug & Play installation.
