I can only agree with the other posters the one from SFS engineering is superb aand the two part model is exactly the same price I did egr bypass at same time and the improvement is great!. £61 might seem a lot but trust me its well worth it. You might want to do the pcv valve filter at the same time mine looked like it had never been done since car rolled off the line at least I now know dipstickbwont try to escape through the bonnet any time soon
