How much power does the HPS Post-MAF Air Intake Tube Kit for Lexus actually add?

HPS measured +14.5 wheel horsepower and +12.6 lb-ft on the dyno, with the gain concentrated in the top end of the power band. The 3-1/2 inch mandrel-bent tube removes the corrugations and steps in the factory rubber piece while holding the air fuel ratio inside a safe window across the range.

Does this fit non-F Sport GS350, IS350, or RC350 models?

No. Part number 27-569 is designed around the F Sport intake tract on the 2013-2019 GS350, 2013-2019 IS350, and 2015-2019 RC350. If your car is a base or Luxury trim, please Contact us with the year and model and we will confirm the correct part before you order.

Will this throw a check engine light or require a tune?

No to both. The tube replaces the section between the mass air flow sensor and the throttle body without moving the sensor or altering the airbox, and HPS validated that the air fuel ratio stays in a safe range. No reflash, piggyback, or tuning is needed.

Does it come with an air filter?

No. The Post-MAF Air Intake Tube Kit for Lexus is the aluminum tube, reinforced silicone couplers, stainless steel T-bolt clamps, and the installation manual. It integrates with the factory fresh air scoop and airbox, so the vehicle keeps using the panel filter already fitted.

How difficult is the installation?

Level-1. The Post-MAF Air Intake Tube Kit for Lexus installs with basic hand tools. The factory tube is clamped at each end, and HPS includes a step-by-step manual with photographs. No cutting, drilling, or other modification is required, and most owners finish inside an hour.

Why can this not be sold in California?

HPS has not submitted part number 27-569 for a CARB Executive Order number, so it carries no exemption. Without an EO number the part cannot be sold in California or fitted to a pollution controlled vehicle registered there.

Description

HPS Post-MAF Air Intake Tube Kit for Lexus GS350, IS350, and RC350

The HPS Post-MAF Air Intake Tube Kit for Lexus GS350, IS350, and RC350 F Sport swaps the restrictive factory rubber intake tube for a free-flowing 3-1/2 inch mandrel-bent aluminum tube, and HPS has the dyno sheets to show what that buys: +14.5 wheel horsepower and +12.6 lb-ft, with sharper throttle response and a safe air fuel ratio held throughout. The tube integrates with the factory fresh air scoop and airbox rather than fighting them, so the engine still draws cool air from where Lexus intended. HPS fine-tuned the design to put the gain in the top end of the power band, which is where a 2GR-FSE actually rewards a driver who uses it.

Development and Testing

HPS tuned the Post-MAF Air Intake Tube Kit for Lexus on the dyno rather than shipping a generic diameter and hoping for the best. The 3-1/2 inch bore was chosen to keep velocity up while removing the corrugations and steps molded into the factory rubber tube, and the result was measured at +14.5 wheel horsepower and +12.6 lb-ft with the air fuel ratio staying inside a safe window across the range. The kit does not require tuning and does not trigger a check engine light.

Construction

Mandrel bending holds a constant wall thickness and internal diameter through every curve, where press-bent tubing crushes and necks down at the bend. Aluminum pulls heat out of the charge instead of soaking it in, and it will not soften, collapse, or split with age the way the factory rubber tube eventually does. HPS pairs the tube with its race proven reinforced silicone couplers and industrial grade 100% stainless steel T-bolt clamps.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
