Yup Im very happy. The combination of the two have made a big difference to my car. Its mostly the torque between 1 and 2,000 rpm where the car now pulls much smoother and strongly. I can now plonk it in straight in 5th from 3rd in a 30 zone and it will easily pull from there. Its meant my around town mpg has risen from 35 to 38 which is nice! Noise wise i dont think theres much difference, just sounds a bit happier when cold. Which is another change, my car used to struggle on cold mornings when i changed up a gear the revs would dip and then rise again giving a light jerking action until it had warmed up. this has now completely gone so I wonder if it was related to airflow. By the way my airbox mod that i did with the laminate plastic has worked great, it has stuck well is well worth the 50 pence it cost!!
