I haven't heard much about the LPE CAI. Would like to know what you all think about them;

What kind of RWHP increase would/should I get?

Can you drive in rain with it installed?????

What about a Tune. Do I need one after it's installed?

Does it have any effect of GPM?

Thanks

 

I have the LPE CAI as part of the Lingenfelter 403 package conversion so I cannot provide any stand-alone numbers resulting solely from the CAI. I certainly have no complaints and I have the utmost respect for Lingengelter products.

I was somewhat concerned about the CAI and driving in the rain. Naturally, right after I installed the 403 I got caught in some moderate to heavy rain. First, the design of the C6 makes it less susceptible to water ingestion than the C5. The mechanics who installed my 403 assured me the LPE CAI could handle all but deep standing water and perhaps torrential downpours. Needless-to-say, driving along at 75 mph through increasingly heavy rainfall I was concerned (I didn't need to hydro-lock my just installed 403 motor). I slowed down, continued to worry and fought the urge to pull off the road. Finally when the rain became extremely hard at one point I did pull-over and called the mechanic for reassurance. He once again told me I would be OK. Still worried I reduced speed to about 65 mph in the heavy rain and motored on. I'm happy to report I suffered no problems whatsoever.

That said (and per LPE's instructions) I still exert caution driving in the rain and I avoid driving through standing water. In fact, if it's going to rain hard...I drive my Suburban. Actually, I believe the owner's manual warns against driving through standing water even with the stock intake.

Changing the filter is a bit involved but really not that difficult. You do have to disconnect the MAF sensor and the plumbing from the throttle body and remove the entire air box. You need to lift the front of the car to remove the airbox fasteners from underneath the car.

I'd suggest checking the LPE web site for specific numbers but as part of the modifications to my car....I'm very pleased with the LPE CAI. The car blasts!

 

I have LPE S\C CAI, I tuned it because of the 100 MAF. LPE said there's a 15 rwhp increase.

 

putting that filter back in after cleaning may require the assistant of a second set of hands.

 

Thank you all for your feedback. I don't plan on driving in the rain either, I will drive one of my other vehicles. The vet stays indoors if there is a chance of rain. Just wanted to make sure incase I got caught in it. Cleaning the filter sounds like a job. Do you use a ramp to lift the front end of the car?

 

Gosh Wayne, that must have been tense - driving home your new creation thinking of the risks in what many have warned against....

I myself have the callaway which is similar to the LPE in how it functions I believe. I too have driven through heavy rain with no problems.

I think it boils down to common sense, as these CAI of today would not be designed and used by some great engineers if there were so many ocurrances of water compromising the systems. I'm glad it worked out for you.

All in all some great things have been reported on the Lingengelter products, including their CAI. It's a no-lose scenario installing one I think.
