The CPR6 high-performance Alloytec V6 inlet manifold is the result of intense development and testing, as well as years of experience with cylinder head airflow research.

Made from high-quality automotive-grade cast alloy, the CPR6 boasts far greater breathing and airflow characteristics than the factory product. Thanks to precision-machined mating surfaces, you're guaranteed proper fitment, right in place of the original manifold and using the factory bolts and hoses.

It'll even fit under your original engine cover!

By simply providing your Alloytec V6 with more air and a cleaner intake path, you'll enjoy power gains of 11%; even on a stock engine! Through extensive dyno testing on real-world vehicles, we've seen gains of up to 60% on modified Alloytec engines.

 

Dyno Graph - Stock/Factory Engine

As you can see clearly from the first graph, gains between 20 and 25rwhp are delivered, even on a stock engine and without an expensive custom tune!

 

 

Dyno Graph - Modified Race Engine

Graph 2 shows the before and after results of fitting a CPR6 Alloytec V6 intake manifold to a highly modified Alloytec. As you can see, even with fully tuned engines, you'll be 45hp off the pace without the CPR6 manifold.

 

 

Fitment of the CPR6 manifold is dead easy and can be performed by DIY enthusiasts of all skill levels using simple tools in around 2 hours!

Not only will your efforts unlock more horsepower, but you'll even save money on your weekly fuel bill, under normal driving conditions. On a standard VE sedan fitted with nothing but a CPR6 intake manifold, testing showed a best of just 8.6L/100km. There's no easier, more potent performance modification you can make to your Alloytec.

If you're looking for that extra edge, when coupled with our 12mm manifold insulators, not only will you raise the tail end of the dyno graph from the CPR6 but peak torque will begin lower in the RPM range. Truly awakening the potential of the under-estimated Alloytec V6.

Excellent Product
It works really well. I used it on quarter tank and drove about 6 miles then filled up with top tier gas and my MPG went up by 3 miles on Highway and about 2 MPG city driving. At first there may be slight hesitation as it clears carbon. Then runs smooth as silk.

So far so good
It seems to be working well, so far. The check engine light turned off and the my vehicle seems to be running well. Be sure to follow the instructions. A while back, I wasted some money on a different catalytic converter cleaner because I put the cleaner in on a full tank of gas. It's best to wait until you're at a half tank or less of gasoline before you put in your catalytic converter cleaner. Also, I drove around right after I put in the catalytic converter cleaner and before I filled up my tank again. A couple of days later, I went to the gas station and topped off my tank. Again, it seems to be running well for now.

Works ok for some stuff.
I tried this mainly to clean my cats. It sadly didn't work for that at all. It did however work great as a basic fuel system cleaner. It smoothed out my idle and cleaned my O2 sensors they were a bit lazy before using this product now they switch fast like they are supposed too. In terms of my recommendation I say use as a fuel system cleaner. Or if your cats aren't too clogged in my case I bought an old neglected used car that likely had that problem for years. So I don't think any pour in tank cleaner would work in my case. However if your car just started having cat issues. This might work?? I think it's worth a try at least and isn't much more expensive than a basic fuel system cleaner so why not?

PASSED MY INSPECTION! THIS PRODUCT WORKS LIKE A MIRACLE DONT HESITATE TO BUY IT!
Inspection on my car due the end of January! My check engine light was coming on so I checked with a code reader & found it was a P0420. Read about the Catalytic Converter System possibly being in need of replacement or perhaps clogged. I am a woman, and know next to ZERO about cars, but I can read. Did investigate and found that the replacement of a Catalytic Converter system is mad expensive- also found this Moly Cleaner to add to gas tank. I'm not going to lie; I was nervous as I have a Kia Rio 2014 that has a very small gas tank and gets great gas mileage. In reading the consensus seemed to be to add to 1/4 tank of gas and drive fast for good periods of time to blow out the clog (if it was a clog). Did I mention I live in NYC and driving for long periods of time at high speeds can be a problem because of terrible traffic. Anyhow, this Saturday I poured the can into my 1/2 filled tank and hit a parkway near my home early morning. I did drive for 45 miles sometimes at 80mph then 60mph but tried to do it for a good few minutes at a time without getting pulled over. Checked my reader again, and it was not quite ready but the engine light did stay off. Next day, drove to work, stuck in traffic somewhat & never made it over 20mph & checked my reader again- all good to go for inspection. Went last night- my car PASSED and got that sticker in my window- so I am good for another year. The BEST money I have spent all year. Thank you for carrying this product! Saved me thousands! DONT HESITATE TO USE THIS. The hardest part for me was removing the cap on the can!
