Quality with lids is a crap shoot ... there's fitment problems with them and they tend to crack over time ... does it happen to all lids, no ... but it does happen and happens more often than people admit. The problems with lids are inherent in the nature of the design and the materials used in thier manufacture.

I don't know of anyone getting 26 rwhp with a FIPK, but 16 to 22 is common. The design and materials of the FIPK guarantee no fitment issues since it is a complete replacement system. As far as cost for an FIPK, PACE typically has them for around $280 and on occasion for sale in the $260 range.

In order to get performance that is going to be equal to the FIPK with a lid, you will have to add a CAI system such as the FTRA or SLP CAI ... by the time you add all the component costs, depending upon which lid, the price will be in the $300 to $350 plus range.

Good Luck

 

Most lid performance inprovements that I have seen range between 10 - 16 RWHP.

No you won't be able to use the FRA concept since the FIPK comes with a plate which bolts inplace of the stock piece that you would cut for FRA.

Also, I would not do FRA with the FIPK since it could allow water to splash against the filter and get sucked into the engine. Perhaps more so than with typical FRA applications (cutting of the OEM parts).

 

26 rwhp gains have happened, take a look at my sig. I'm glad you included the pricing information for buying a K&N FIPK at a discount, the cost of the unit is a little steep!

Very good info. But I still believe the design of the FIPK would allow more airflow. The FIPK would provide cool air to the engine provided its moving. Which works for me since I have yet to make a trip to the drag strip, road racing and cruising for me

Do you know of any examples of 20+ rwhp gains with a lid and CAI or FTRA?

 

Its the lid that came with the 345 hp package... It has the donaldson filter and is known to flow better than the other lids. Youll have to order it from SLP Engineering, not from SLP Performance Part. There is a difference. SLP Eng. deals with OEM Material

 

I don't think that is true for the 2002 LS1 FIPK. It sits right up in the same place as the stock air box, and unless you have a ram air hood, it isn't going to pick up cold air. That is why I think the lid/filter/FRA combo may be a little more powerful. If the FIPK works with the FTRA or FRA, I would definitely change my stand, but I don't think it does.

 

Actually the air flow to the FIPK is the same as it is for the stock air box ... it just makes more efficient use of the available air. And the air flow design does provide cold air once you are moving - through the grill nostrils, up through the bumper, splashing against the hood and directly toward the airbox opening/FIPK filter element.

You can use the !FRA with the FIPK if you want. Either cut the FIPK shroud or use your stock shroud (yes you can use it with the FIPK - looks like crap, but it works). And water exposure with the !FRA on an FIPK is no more or no less than it is with a lid.

But, if you want to do something even more effective with the FIPK, do the "FIPK !FRA". Drop your washer reservoir and the shroud underneath ... why settle for 2 "inch" x 14" opening delivering air that is drawn across a hot radiator, when you can have a 2 "foot" x 14" opening delivering fresh air directly to the front of the filter element ... I picked up nearly 2 tenths with this !mod.

Mister Will ... Didn't see your sig congrats on the gains.

Seems your leaning toward a lid set-up as you said in your original post So I'll post for discussion purposes. The K&N FIPK filter is located were the stock air box usually sits. Therefore it will receive the same air the stock set-up will receive. This air comes from the air-dam under the radiator which directs air from under the car to the radiator and the engine intake. The FIPK takes the same air supplied to the stock air box while allowing a much greater volume of air into the engine. FTRA and FRA will allow even more unobstructed air to the intake of both stock and FIPK equipment. However their applications will also allow water and road debris to the intake as well. This is the dilema with FRA and FTRA.

Also, the FRA and FTRA applications only supply air to the filters. They don't have a true ram air effect.

BTW, I don't believe K&N FIPK will fit with SS ram air hoods. I'm not sure about WS6 ram air hoods.

I would like to hear of the performance gains of FTRA with lid applications?

Yeah, what he said I've got to start typing faster

 

Here's another option. It's a Volant CAI.

All the aftermarket lids use the stock sized MAF housing diameter except for the 85mm TSP lid. If you want to know the stock diameter measure it yourself (donkey responses get donkey answers). I don't know the stock MAF's diameter off the top of my head. Its smaller than 85mm hows that .

 

The Black wing lid from SLP can only be bought useing a vin# from a SS, plus all the aftermarket lids flow better, it still has the same oval opening the stock lids have, the aftermarkets have a nice large round opening for improved flow....not to mention how much it would cost from SLP compared to the aftermarket.

 

The stock lid & MAF are 75mm. More airflow with the 85mm comes in handly especially with heads/cam.

 

ya.. I forgot to mention that you need either an SS or Firehawk VIN... Oh well... I would like the BlackWing lid but for around the same price you can get the SLP PP FlowPack (CAI, PP LID, and other crap) Tough choice though if ya want it to look like OEM Material...

 

That looks like it is designed for use with an aftermarket Ram Air hood. Looks like it would be pretty effective too.
