Decarb intake manifold

[nat225]

It's better than nothing, which is what 99% of cars get. For sure it's like brushing your teeth vs visiting the dentist for that awesome and fun ultrasonic clean, but who honestly has time to take the whole mani off routinely? I've pulled mine once, and I was happy my car buildup is low, so cans for me in-between, and a pull every 50 thou / Christmas holiday or so. But then I run serial catch cans, further helping lower the problem.

very well said!

keeps me motivated to use fuel additive every 3 months and upper intake cleaner regularly

I also try to drive Brisbane / Gold Coast return (when I need to go down there) to help burning off the carbon regularly.

if this helps to extend mileage before the real need to do the hardcore removal of the intake manifold, I'd be happy

The problem is not the intake itself , that just reduces performance . The problem is the injector tips getting carbon build up . No matter what fuel additives you use there is nothing thats going to prevent carbon build in the combustion chamber . Catch cans will only prevent carbon build up up to the valves .

I find the best trick is to make sure you use all the various colours of fuel additive at Supercheap over a year, and I try and cycle green, red, yellow and blue. I reckon colour cycling is the answer.

Good fuel additive also takes care of it.

My mech. just sent me this. 50,0000km GTI with 6 monthly chip fat changes. Car has done plenty of highway and also plenty of stop/start inner west driving...

I'd run an intake cleaner through it every 15K, and pull the manifold off for a proper clean when (not if) the water pump leaks, and needs replacing.
