PRL SRI Conversion to Cobra CAI Performance/Review

[gylmar814]

What's up everyone, for some time now I had the PRL SRI, didn't want to go with the Cobra CAI version at first because I wasn't sure how it would hold up with South Florida rain/showers. After doing further research and seeing everyone elses input on the CAI I decided to pull the trigger and purchase the conversion to turn my SRI to the CAI, besides I figure it would pair up nicely with the PRL Intercooler I already have installed...

I couldn't believe how drastic of a change my IAT1 went down after installing and driving ! I drove for about 30 minutes with spirited driving in between with 3rd and 4th gear WOT pulls... My IAT1 actually stayed lower than my IAT2 the entire time driving by a good 10 degree margin. Something I never saw in my car before. On average I was getting 20-30 degrees lower in IAT1 compared to the SRI, that's huge. Not to mention, the difference of power I felt throughout the RPM band... This is the first time I actually feel a difference in power on the butt dyno from just an intake on any vehicle! However, I did feel low end torque took a slight drop which I expected from a CAI...but once I passed right around 3k in the RPMs, the car really woke up.

Overall, the PRL Cobra made a big change & compliments the PRL Intercooler so well, I actually have a bittersweet feeling from it because I feel the Cobra Intake actually has more of a positive effect in regards to what it did to the IAT1 compared to what the Intercooler did with IAT2... but I'm sure that's because of the burst of pulls and braking I did. I was limited with the space I was given because of the traffic and city driving .

Install was a breeze and everything lined up just perfectly. Some of the stuff you guys wrote about this Intake you weren't kidding... The Cobra Intake exceeded my expectations from just an intake. @PRL Motorsports , you guys did a stellar job with this project. Thank you !

glad you went the CAI route, the differance in IATs are great compared to stock IATs

Awesome, glad to hear everything has met/surpassed your expectations! We cannot stress enough how critical a proper CAI is for these cars. Thanks for the data and review!

Okay I thought this was a me thing or it was just cause I don’t have a tune, but this is my first CAI and wasn’t sure if this was a normal occurrence that happens with them.

It usually does. atleast with my experience with them. I think the theoryh behind it is because with short rams the throttle response is quicker and the air goes in the intake manifold quicker. I know PRL claims the Cobra doesnt require a tune and provided data sheets showing fuel trims almost Identical compared to the stock setup

@gylmar814 do you know if this will void the warranty?

@gylmar814 do you know if this will void the warranty?

If I’m not mistaken, it’ll only void warranty if the dealership can prove that an issue occurred due to the CAI. I’m not sure what they check out exactly, but I’ve brought in my car into my dealership a couple times already for an oil change and state instpection and they haven’t said a thing about mine.

@gylmar814 do you know if this will void the warranty?

It all depends on the dealer that sees it, what mood they're in that day, and if anything goes wrong with the powertrain down the road, they can prove the intake played a role in the damage or defect.

Technically there is no straight forward answer but if it helps, it's more yes than no when asking if it voids the warranty. You can also always reinstall the stock intake when taking it to the dealer for whatever reason

@Legato @gylmar814 do you feel any difference on the top end of the power band (4k rpm and higher) ?

 

[fiend busa]

I wish there was an option to custom order the CAI intake to fit the Canadian without doing the USDM swap.

I'd definitely pay extra $$ for it @PRL Motorsports

Did you not read my review? Lol.

Yes, you you feel the rpms pull stronger once you pass 3k rpms
