“I have had the PRL CAI for 6-8 months and I absolutely love it! Was the first mod to my 10th gen Si. Two step performance has the best customer support as well!”
“I finally got a PRL CAI SI RACE MAF, and I already had K tuner just had to upload the TSP 1 RACE MAF tune and it worked with no problems. Hissing sounds and turbo discharge sounds just put smiles in my face. Love it.”
“TSP is a great company, support 2nd to none, prices on point. got the race maf and tried to drive before tune, dont it doesnt work well. Luckily i was at home so just tuned it 1st. Wish it came with instructions, took a minute to find them online. Fits great, works great, not too loud, but can finally hear the turbo sucking LOL.”
“Great quality CAI. Pretty easy install, just watch some Youtube videos. I'm very happy I decided to buy this. I got the street version for my Si, and the sound to me is perfect. You don't hear it if you're just casually driving, but once you get on it a bit, it'll put a smile on your face.”
“Absolutely amazing product. Once it was processed I had the part in 2 days. Makes the car sound a lot better, I also noticed it pulled a little harder in upper mid-high ranges. Will definitely be doing business with them again along with recommending them. Of course the favorite extras are the stickers provided and to my surprise a license plate frame”
