Top quality finish
These are far superior than the stock plenums
The finish is top quality also
Arrived in Australia with no damage and good time
Will definitely be buying from RiffRaff again -
Quality far surpasses stock
I was surprised to see how flimsy the stock plenums are, no wonder they leak! The fit perfectly and are very high-quality. If you have the turbo off, I would highly recommend replacing these while in there. The O-rings are such an upgrade compared to screwing around with messy RTV.

Awsome product
Installed my plenums at the same time I done the evbp delete which is the best time do it all at the same time I also done the banjo bolts,cvd fittings & the boot & new clamp along with the pedestal bolt kit & turbo install kit

Great Quality
Did this job at the same time as a Turbo/EBV pedestal delete, pretty straight forward once everything is removed. I ended up just removing the fuel bowl for extra room. Used a Dremel with a cut off wheel to remove the passenger side plenum bolt that hits the HPOP and can't be backed out. Really happy with the quality of all Riffraff products.

Riffraff products are the best
The quality of these plenums is excellent. I've ordered several parts from here and everyone has impressed me. If you need injector cups don't even hesitate to rent the installation tool ease of use and quality of tool makes this job so much easier

Since we're in there
The new plenums were ordered after I pulled the turbo out and was doing other work. Fast shipping, helpful advice and the most beautiful billet work I have seen in a long time. That coupled with a very reasonable price means you cannot go wrong. The hardest part of the manifold change was which color to pick. We are breathing life back into our 450,000 mile unit. Thank you Clay and Crew.

Top Notch Billet Plenums
I decided to purchase these plenums since I was tearing apart the top of the motor to do a bunch of upgrades. These plenums are very high quality and having them with the Viton O rings makes them super nice. Comparing them side by side with the stock plenums you can see they have much better air flow. Do yourself a favor if your also installing the fuel rail cross over at the same time, once the stock plenum is off and before installing the billet plenums remove the 2 fuel plugs on the heads for the crossover. Its much easier at this time while the plenums are removed.
