I have been considering getting a PRM but I'm not sure. Company insurance is an obvious one, but more the heat issues. Although I love the sound when driving with the airbox cover off, I tend to get it back on asap as I really feel the performance loss. I also worry about the kangarooing in traffic as I get with the OEM air filter.

After reading quite a lot of threads about the PRM I also cames across

The AEM CAI. For

 

AFAICS the AEM (and similar) are proper cold air intakes cos they take the air in from in front of the radiator.
The PRM isn't a CAI cos it's still sucking up hot air from the engine bay. It may well sound nice but it aint gonna stop kangarooing from heat soak.

From what I've read the AEM type of intake provide the most power gains - albeit still pretty minor (3-4bhp tops).

Am sure somebody will be along to say otherwise shortly though!

 

PRM sound is much better than air box cover off , plus you don't loose any performance IMO. You need to here one before making your mind up. I did and bought it the next week , its great

I dont have any kangarooing its an urban myth I reckon.

BTW my insurance company dont mind mods, I pay no extra for PRM, 18's , diff suspension and I have asked about HKS exhaust, they say no charge

 

I think the thing that puts people off a "proper CAI" e.g. Injen, AEM or 4IG is the fact that you have to cut a small hole in the plastic undertray to allow the pipework into the area behind the faux grill, where the air filter is mounted. Another "issue" is hydrolocking, whereby water is sucked into the engine via the air filter, with it being mounted so low to the ground.

I have the 4IG and have no prolem with either of the above "issues". Like tims says, for me the PRM is not a proper CAI. The others listed above are, because the air is now drawn from a new position outside of the engine bay.

Oh, and then there's the sound . The PRM does sound good, but I wanted more than just a sound improvement. With the 4IG there is improved throttle responce and no kangerooing, and still a great noise. As the 4IG is no longer available I would go for the Injen or the AEM.

HTH

Cheers everyone, the one thing I don't want is any work or cutting to the car! Mmmm I am going to have to think about this, I'm not bothered about performance gain just noise really. I will see what the company insurance says tomorrow and I think I might join the GB for the PRM if I get the all clear

 

So if it doesn't happen to you, it's a myth.....?

It's far from mythical. Take my word for it.

 

Course I've always thought that the Lurking Lawyer was in fact a clever AI program and as such, just a myth.

 

Well, I agree with most of your statement

 

I decided to go for a PRM for the following reasons:

- Noise!
- Power 'neutral' - you dont loose any, but you probably dont gain any either.
- No cutting of car required - I can have my car back to 100% stock in 15 mins.
- No Hydrolocking issues.
- Reduced 'bogging'.

I have not been disappointed, however despite my initial reluctance to make permanent mods to the car, I have had the faux vents cut out and have fitted a Coastal Metals Airflow kit (posh name for a couple of nice grills!) - the extra airflow into the bonnet area, and specifically the mouth of the PRM, has all but eliminated heat soak induced bogging.

Oh.....and it saves you a bit of money long term as it is supplied with a K&N style cleanable air filter.

 

I did exactly the same and never had any problems with my PRM.

Hydrolocking is a worry and sticking something in front of the radiator is going to mean more work for the fan to keep the temp down.
