I'm running the CSF intercoolers and I'd be lying if I said I wasn't disappointed.

I've been data-logging IATs since I bought the car - both with stock intercoolers and, more recently, with CSF and I haven't seen a meaningful difference in IATs - certainly not of sufficient magnitude to justify the price.

I was persuaded to buy after watching the Evolve comparison which showed a significant reduction in IATs when running the CSF coolers. Those improvements are regrettably not evident on my car. Maybe I'll see better gains in the mid-summer heat although I've been testing on days when ambient is not too low (22 - 28 degrees Celsius)
