Hi
Anyone have an opinion on this air filter for my C8?


1001-200T 2020-25 C8 Corvette Attack Blue® Dry NanoFiber Performance Filter/ LT2 - Lavenza

From tko performance

thanks

 

Some feel it gives them a couple extra HP and a little more sound. I feel it's a placebo. I use the stock filter. There are vehicles that benefit from aftermarket filters but don't feel the SR is one.

 

Personally, I like K&N and AFE (run them both in personal cars). K&N has been an OE supplier for certain specialty vehicles for manufactures over the years.

On C8 there are dynos of 5-10 whp gains - I suspect it has more to do with different dynos than filter performance. But you can expect a small power bump, quicker throttle response and increase acoustics.

 

Yes, I see the change already once installed. Feels much quicker. The sound is definitely different/louder.I think this type of filter made a difference.

 

Wait. In your first post you are asking what kind of performance increase you should expect and then A couple hours later you say you have it and are getting a great performance increase?

Are you trolling?

 

Feels quicker according to your butt dyno?

 

Only thing I didn't like about the Attack Blue is the recommended 10k mi service interval and 50K mi life. I went with a K&N drop in on my SR.

 

In my first post, I asked if anyone had an opinion about that type of air filter.


The filter came in. I installed it. Power seems great and exhaust sound is a little more funky.I’m 70 years old. I’m not sure what I’m trolling about. I’m only asking people’s opinion.

 

The high performance air filter install benefits have been debated for decades ....doubtful it will now make you win races that you had been losing if that is your quest . On the other hand if its your desire to really get some HP , yes a good filter is a must in the process of bolt ons

 

No, I’m not in the habit of racing on the open road.
But I’m confused to your reply. Are you saying this type of filter could make a difference in increased horsepower or is it just one’s imagination?
I suppose I could have run before and after test of 0 to 60 to see if there was any improvement.

 

doubtful just an airfilter is going to be felt but when used as part of an add on plan........intake,throttle body ,CAI ,headers ,cats ,pipes and tune , the trick is to install things that work [proven] together as a plan ......what is your plan or why do you feel [pun] the need for more power . Are you going to drag race or road race ....they aint the same rpm power band wise

 

I put the blue attack filter in...to me, waste of time and $$. No sound difference and the hp gain is not enough to feel. I am keeping it in, but the OEM filter is fine. Just my opinion.

 

Your second post about how well the air filter performed was a few hours after you posted asking if it was a good upgrade. Just seemed odd, how many times does someone appear to post a question and then an answer like that same day when they have to order, receive, install, and test an item?

Still seems off to me but good on you for doing that all in a few hours.

 

I’m retired, plenty of time on my hands. I get a part. I install it. I’m not trying to create animosity here, but I think you’re overthinking this issue. I was only asking people‘s opinions of that particular air filter. To delve into why I’m asking or did I already have it installed or how did I get it installed so quickly is pretty trivial. This is my final reply on this issue. Thanks to everyone for any input.

 

Paragon Performance did an air filter dyno shootout on the same day with same fluid and air temps. Why is the same fluid and air temps important? Because air and fluid temps can affect hp and torque and skew the results.

The dyno resulted with both the Attack Blue and AFE dry air filter increased horsepower in the upper rpm range (5300+rpm) by 5-6 HP. Torque increase of 2-3 ft-lbs pockets in the lower and mid rpm range and throughout the upper rpm range.

I swapped out the oem air filter for AFE dry air filter. My conclusion: I heard a little more air intake noise off idle and when the DCT downshifted with a throttle bleep. Did I gain 5hp? Probably. Did I feel it? No.

 

5hp out of 500? 1%. Probably less than the measurement uncertainty. Not to say they may not have made the 5hp but in reality it's more a marketing thing than a realistic gain.

 

By keeping the same parameters, measurement uncertainty was negligible. However, Paragon did say when it was time to change the air filter any of the tested air filters would be a good option. Yes, Paragon sells the air filters, but the point of the dyno shootout was simply a comparison test. The conclusion was that the reputable aftermarket air filters are good for around 5 rwhp in the upper rpm range. I have seen several third-party testing with similar results who are not retailers. It's good to have options

 

Just out of curiosity, what do you think the measurement uncertainty would be? If you did five pulls with the same car no changes in between? Any idea? 1%? 3? 5?

 

I've been putting on CAI on almost every performance car I've had since my 2005 GTO with the 'mighty' rotofab, same for my G8 GXP, a couple of Mustangs.

Why did I do this, well the parts were relatively cheap, and it looked simple to do. After my GTO and GXP, it occurred to me that there was more of a noise than before, but no really horsepower pickup. Not being an auto mechanic, I think I did it because there may be a horsepower bump, but more importantly it felt good actually working on my car even if it was something as simple as installing a new box for the filter and slipping the filter on the new tube.

On my C8 Z51, I looked many times at youtube videos and it seemed there were a lot of 15 torx and a few bolts, so I just said, the juice isn't worth the squeeze. So one night I was watching one of those replace air filter on a C8 videos, said to hell with it, made sure I had the proper 15 torx, and ordered it. The whole thing took around 45 minutes and there was really nothing to it. Had I had a proper tool to pull up the pins, it would've been less than 30 minutes to do it. Did the new blue Attack filter make a difference, probably not, but the completing of the job had a far greater sense of accomplishment than the filter did.

 

430 rwhp with a 5 rwhp gain = 1.16% measured uncertainty with aftermarket air filter.

Tell me with no changes.
