We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner

This Blow Off, or dump valve, is for the Renault and Nissan Turbo engines that have the electronically controlled bypass valve (OEM Part no. 144839204R). It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred. Unfortunately, the failure doesn’t always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this. This prevents the diaphragm from sealing.

Our alternative is a fully engineered solution offering both significantly improved reliability. The Forge valve is piston based, there is no diaphragm to fail, and of all aluminium billet construction, it replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control, over valve actuation.

Extremely strong magnets
Color: Orange
The magnets are extremely strong. You almost have to slide it off the metal surface to remove.

Excellent Tool For Drilling Shelf Pin Holes
I had a project where I was extending the depth of the bottom half of a bookcase I had made out of pre-drilled MDF from Home Depot. The original bookcase was 11" deep x 10' high. The extended depth of the bottom is to be used to hold audio gear and needed to be 18" depth, front to rear. I was able to increase the depth but had to insert additional panels on the left and right so that shelf pins could be installed. I needed a shelf pin jig to do that, and this jig was perfect for the job. After completing my holes and mounting some shelves I was pleased that the alignment with the inner portion of the shelf was perfect and the distance between holes lined up exactly as with the original panels from Home Depot. The jig is high quality fabricated aluminum, not plastic, and it comes with two drill bits, and stop and Allen wrench, including an instruction manual, all in an attractive plastic case. The jig is well worth the modest price and I would definitely recommend it for drilling shelf clip holes.

a solid choice
I realized I don't need to drill 5mm holes, so this item is just perfect. It's higher quality than those other cheap-chinese noname jigs. In particular: * The stop collar provided actually fits the drill bit. I had one from Tanyo that had too-big collars that didn't stay put. * The fence pins are very soilid, so the jig doesn't move while in place. Other brands have a long knurled screw that wobbles and allows the kiig to move around. * The plate is thick, making it feel sturdy. * It's phyically smaller than the others, because it doesn't have any useless features like euro-hinge hole guides. The case is more compact and stores well. Overall, very satisfied with this jig.
