Had a few extra minutes today and discovered I had an extra JWT POP Charger Filter laying around. So, I decided to slap it on my newly-acquired NA. I was pretty shocked at the differences: Car ran smoother and quieter at idle and she felt much peppier when I drove her to lunch. The stock filters were a bit dirty and I also cleaned the MAF with some CRC MAF cleaner. Just wasn't expecting to feel such a difference. She's much funner to drive now:) That is all.
