15’ LML hot and cold side pipes.

Great product easy to install. Good bang for your buck. Will continue to purchase more products from here. Agree with everyone else on the couplers but for the price not that big of a deal.

Hi, thanks for the comment and pictures! Looking forward to your next purchase!

Good pipes, needs better couplers

The intercooler pipes are really nice, however during my install I found the clamps too small by 8mm and the turbo clamp was way oversized. Other than those short comings it is a nice kit.

Thank you very much for your feedback and suggestions, spelab will optimize this product.

Clamps!

Pipes themselves are great! Smooth bends and fit properly. 3 clamps are too small for lml and 1 clamp is too large. Boot to intercooler clamps provided will only fit without spring, boot to intake clamp only fits without spring and boot to turbo is too large as it's the only 2 1/2" connection but they expect you to use the same size clamp as the 3" spots.
Sent email to spelab but no response so I had to buy 3 mishimoto clamps seperately.

Thank you very much for your feedback and suggestions, spelab will optimize this product.
